Given that the coin has a grade of 75 (MBC), indicating good quality, and considering that it is being auctioned for the first time, the starting price is set at 300 euros.

In this case, since there are no historical sales data for this coin, we can estimate a maximum purchase price based on the starting price and the grade.

Generally, in auctions, final prices can vary between 1.5 to 2 times the starting price for coins in good condition. Therefore, an estimated maximum purchase price could be between 450 and 600 euros.

However, since the starting price is 300 euros and there are no sales records, a more conservative estimated price could be around 450 euros.

Thus, the estimated maximum purchase price would be approximately 450 euros.

To estimate a maximum purchase price for the coin in question, we will consider several factors:

1. Current Condition: The coin has a condition rating of 75 (MBC), indicating that it is in relatively good shape, but not among the highest qualities.

2. Auction History:
- The average hammer price in previous auctions is 183.29 euros.
- The coin has been auctioned 18 times, of which it has sold 17 times, indicating good demand.
- In previous auctions, hammer prices have varied, but there are examples of sales reaching up to 420 euros in similar conditions (condition rating 85).

3. Starting Price and Estimates:
- The current starting price is 200 euros, which is slightly higher than the average starting price of 144.17 euros.
- The estimated price for this auction is 300 euros, suggesting expectations for the coin to reach a higher price.

4. Price Trends:
- In the most recent auctions, hammer prices have ranged from 255 to 300 euros for coins with similar conditions (condition rating 85).

Based on these factors, an estimated maximum purchase price could be in the range of 250 to 300 euros. This is because, although the condition is not the highest, demand and price history suggest it could reach a competitive price.

Therefore, a reasonable maximum purchase price could be approximately 280 euros.

To estimate a maximum purchase price for the coin in question, we can consider several factors based on the provided data:

1. Current Condition: The coin has a condition rating of 75 (MBC), indicating a medium-good quality. This suggests that its value should be in an intermediate range, but not at the highest level.

2. Auction History:
- The average hammer price in previous auctions is 294.47 euros.
- The coin has been auctioned 20 times, of which it has sold 17 times, indicating good demand.
- Previous hammer prices for coins with similar condition (75) have varied, but there are examples of auctions reaching up to 375 euros.

3. Starting Price and Estimates:
- The current starting price is 250 euros, which is a reasonable starting point.
- The estimated hammer price for this auction is 350 euros, suggesting that bidders are willing to pay more than the starting price.

4. Recent Trends: In the most recent auctions, hammer prices have been around 200-300 euros for similar conditions, but there are also examples of higher hammer prices.

Based on these factors, an estimated maximum purchase price could be around 350-400 euros, considering that the coin is in good condition and has shown a hammer price history that supports this figure. However, since the market can be volatile, it is advisable to keep an eye on the competition in the auction.

To estimate a maximum purchase price for the coin in question, let's consider several factors:

1. Condition: The coin has a condition rating of 80 (MS+), which is a good condition and can positively influence its value.

2. Auction History:
- In the past, this coin has been auctioned 3 times and has sold on all occasions.
- Previous hammer prices have been 420, 300, and 260 euros, indicating that interest in the coin is consistent and that it can reach high prices.

3. Starting Price and Average Prices:
- The current starting price is 300 euros, which is above the average starting price of 208.33 euros, suggesting that the seller has high expectations.
- The average hammer price is 326.67 euros, indicating that, on average, similar coins have reached prices close to this value.

4. Recent Trends: In the last auction, the hammer price was 260 euros, which could indicate a slight decrease in interest or in the value of the coin compared to previous auctions.

Taking all these factors into account, an estimated maximum purchase price could be in a range between the average hammer price (326.67 euros) and the highest price reached in the past (420 euros).

Therefore, a reasonable maximum purchase price could be approximately 350-400 euros. This allows for a margin for competition in the auction, considering that interest in the coin remains high.

To estimate a maximum purchase price for the coin in question, we will consider several factors:

1. Current Condition: The coin has a condition of 70 (VF-). This is an important factor, as coins in better condition tend to reach higher prices.

2. Current Starting Price and Previous Prices: The current starting price is 75 euros, and the average hammer price in previous auctions is 131.05 euros. This suggests that, in general, coins of this reference tend to sell for above their starting price.

3. Auction History: In the auction history, it is observed that coins with similar conditions have reached hammer prices that vary, but many are in the range of 110 to 140 euros. For example, in 2020, a coin with a condition of 80 was sold for 110 euros.

4. Recent Trends: In the most recent auctions, hammer prices have been in the range of 120 to 160 euros for similar conditions.

5. Average Hammer Price: The average hammer price of 131.05 euros also indicates that, in general, buyers are willing to pay more than the starting price.

Taking all these factors into account, an estimated maximum purchase price for this coin could be around 130-150 euros. This is based on the hammer price history and the current condition of the coin. However, it is important to remember that the final price may vary depending on the competition in the auction and the interest of collectors.

To estimate a maximum purchase price for the coin in question, we will consider several factors:

1. Current Condition: The coin has a condition rating of 80 (MS+), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Previous Prices: By looking at previous auction prices, we can see that in the most recent auction (2023), the coin sold for 1800 euros, suggesting that there is significant interest in this coin in its current state.

3. Starting Price and Average Hammer Price: The current starting price is 1500 euros, and the average hammer price in previous auctions is 1230 euros. This indicates that the starting price is higher than the average hammer price, which may be an indicator that the seller expects greater interest in this auction.

4. Sales Trend: The coin has sold every time it has been auctioned, suggesting that there is consistent demand.

Based on these factors, an estimated maximum purchase price could be positioned in a range between the highest previous hammer price (1800 euros) and a bit more, considering the good condition and interest in the coin.

Therefore, an estimated maximum purchase price could be approximately 1900 to 2000 euros. This would allow for competitive bidding in the auction without exceeding a reasonable limit based on the sales history and current condition.

To estimate a maximum purchase price for the coin in question, we can consider several factors based on the provided data:

1. Starting price: 90 euros.
2. Average hammer price in the past: 160 euros.
3. Condition of the coin: 75 (MBC), which is quite a good condition.
4. Auction history: The coin has been auctioned once before and sold for 160 euros.

Given that the average hammer price in the past was 160 euros and considering that the condition is the same (75), it is reasonable to assume that the hammer price could be in a similar range.

Additionally, since there is an auction scheduled in the coming days and the coin has a history of successful sales, this could increase interest and competition among bidders.

Taking all these factors into account, an estimated maximum purchase price could be around 160-180 euros, as this reflects the previous hammer price and allows for a small margin for competition in the auction.

Therefore, an estimated maximum purchase price would be 180 euros.

To estimate a maximum purchase price for the coin in question, we will consider several factors:

1. Current Condition: The coin has a condition rating of 75 (MBC), indicating that it is in quite good shape. This generally increases its value compared to coins with lower conditions.

2. Starting Price: The starting price is 110 euros, suggesting that the seller has high expectations for this auction.

3. Auction History: The coin has been auctioned once in the past, with a starting price of 30 euros and a hammer price of 30 euros. This indicates that, in the past, the coin did not have high demand, although the current starting price is significantly higher.

4. Average Hammer Price: The average hammer price in the past was 30 euros, suggesting that despite a higher starting price, the actual interest from buyers may be lower.

5. Auction Expectations: Since it will be auctioned again in the coming days, and considering that the starting price is 110 euros, it is possible that buyers may be willing to pay more than the previous average hammer price, but not necessarily the full starting price.

Taking all these factors into account, an estimated maximum purchase price could be positioned between the previous average hammer price and the current starting price. A reasonable range could be between 50 and 70 euros, considering that the condition is good and there is potential interest, but also that the auction history does not support a hammer price as high as the starting price.

Therefore, an estimated maximum purchase price could be 70 euros.

3. Price trends: The average hammer price in previous auctions is 74.05 euros, but there are examples of sales that have exceeded 100 euros. This suggests that there is potential for the coin to sell at a higher price, especially considering its good condition.

4. Supply and demand: Since this coin has been auctioned 20 times and all have sold, this indicates good demand. Additionally, it will be auctioned once more in the coming days, which may influence competition and the final price.

Taking all these factors into account, an estimated maximum purchase price could be around 120-140 euros. This is based on the good condition of the coin and previous hammer prices that have exceeded 100 euros. However, it is important to consider that the final price will depend on the competition in the auction and the interest of collectors.

Previous Hammer Prices: Looking at previous hammer prices for coins with a similar condition (80), we can see that they have reached hammer prices that vary, but some have reached 190 euros (in 2018) and 250 euros (in 2022). This suggests that there is significant potential for a high hammer price.

5. Recent Trends: In the most recent auction, a coin with a similar condition sold for 340 euros, indicating that the market may be on the rise.

Based on these factors, an estimated maximum purchase price could be in the range of 150 to 200 euros, considering that the condition is good and that the sales history supports a higher price. However, given the recent market behavior, a maximum purchase price of 200 euros could be a reasonable estimate.

To estimate a maximum purchase price for the coin in question, we will consider several factors:

- The average starting price in previous auctions is 16.11 euros, suggesting that the current starting price is quite optimistic.

4. Price Trends:
- Given that the condition is good and there is a history of hammer prices suggesting that the coin could reach higher prices, it is reasonable to consider that the hammer price could be in the range of 20 to 30 euros, depending on competition in the auction.

Based on these factors, an estimated maximum purchase price could be between 25 and 35 euros. This takes into account the good condition of the coin and the demonstrated interest in previous auctions. However, since the starting price is 30 euros, it is likely that the hammer price will not significantly exceed this value unless there is strong competition. Therefore, a prudent maximum purchase price could be 30 euros.

3. Starting Price and Estimated Price:
- The current starting price is 75 euros, which is higher than the average starting price of 50.83 euros. This may indicate an expectation that the coin will sell for a higher price due to its good condition.
- The estimated price of 90 euros in a previous auction (2018) also suggests that there is potential to reach higher prices.

4. Sales Trends: Of the 18 times it has been auctioned, 12 have resulted in sales, indicating a consistent interest in this coin.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 90 to 130 euros, considering that the condition is good and there are precedents for high hammer prices. However, to be conservative and taking into account the starting price, a reasonable maximum purchase price could be 100 euros. This allows for competition in the auction and reflects the interest in the coin.

To estimate a maximum purchase price for the coin in question, we can consider several factors:

- Previous hammer prices are relevant. For example, in 2016 it sold for 110 euros, establishing a high benchmark. In 2022, it was auctioned with a starting price of 50 euros and an estimated price of 75 euros, indicating that the market is willing to pay more for coins in better condition.

3. Starting Price and Average Prices:
- The current starting price is 75 euros, and the average hammer price in the past has been 71 euros. This suggests that the starting price is reasonable and could attract bidders.

4. Market Trends: Given that the coin has a history of hammer prices that vary, and considering that the condition is good, it is reasonable to expect that the hammer price could be above the starting price.

To estimate a maximum purchase price for the coin in question, we can consider several factors:

1. Current Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in quite good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The average hammer price for similar coins in the past is 71.8 euros.
- The coin has had hammer prices that vary, with the highest being 260 euros in a previous auction with a condition of 85.
- The price trend shows that coins with a similar condition (80) have reached hammer prices of up to 135 euros.

3. Starting Price and Estimated Price:
- The current starting price is 75 euros, and the estimated price is 150 euros. This suggests that there are expectations for the coin to sell for a considerably higher price than the starting price.

4. Demand and Supply: The coin has been auctioned 31 times, of which 20 have resulted in sales. This indicates a consistent interest in the coin, which may influence the price.

Based on these factors, an estimated maximum purchase price could be in the range of 120 to 150 euros, considering that the condition is good and there is a history of hammer prices that supports this estimate. However, given the starting price of 75 euros, it is likely that buyers will be willing to bid more, especially if there is interest in the coin.

Therefore, a reasonable maximum purchase price could be 150 euros.

Given that the coin has a condition of 75 (MBC) and has not been auctioned or sold in the past, the starting price is 75 euros.

Without historical sales data for this reference, it is difficult to establish a maximum estimated purchase price. However, considering that the starting price is 75 euros and that the condition is good (MBC), you could consider a maximum estimated purchase price that could be in the range of 1.5 to 2 times the starting price, depending on collector interest and demand at the auction.

Therefore, a maximum estimated purchase price could be between 100 and 150 euros. This is just an estimate, and the actual price may vary according to the dynamics of the auction.
