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 (MS+), indicating that it is in relatively good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The average hammer price for this coin in the past is 164.14 euros.
- The coin has been auctioned 38 times, of which it has sold 28 times, indicating good demand.
- Previous hammer prices varied significantly, with some reaching very high prices (for example, 600 euros in a previous auction).

3. Starting Price and Average Starting Price:
- The current starting price is 70 euros, which is relatively low compared to the average hammer price.
- The average starting price is 103.28 euros, suggesting that the current starting price could be attractive to buyers.

4. Recent Trends: In the most recent auctions, hammer prices have ranged from 55 to 100 euros for similar conditions.

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 price history shows that coins in similar conditions have reached higher prices in the past.

Therefore, a reasonable maximum purchase price could be 180 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 80 (MBC+). This is an important factor, as coins in better condition tend to fetch higher prices at auctions.

2. Starting Price and Previous Prices: The current starting price is 100 euros. The average hammer price in previous auctions is 87.76 euros, indicating that, in general, coins of this reference tend to sell for below their starting price.

3. Sales History: Out of the 47 times it has been auctioned, 37 have been sold, indicating a sales rate of 78.7%. This is a good indicator of demand.

4. Previous Hammer Prices: Looking at previous hammer prices, there are several examples of coins with similar conditions that have sold for prices that vary significantly. For example, in 2015, a coin with a condition of 80 sold for 151.65 euros, and in 2022, one with a condition of 85 sold for 210 euros.

5. Recent Trends: In the most recent auctions, hammer prices have shown an increase, which could indicate an upward trend in the value of these coins.

Based on these factors, an estimated maximum purchase price could be in the range of 120 to 160 euros. This is based on the fact that, although the starting price is 100 euros, the condition of the coin and the price history suggest it could reach a higher price at auction, especially if there is interest among collectors.

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

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

1. Starting price: 60 euros.
2. Condition: The coin is in a condition of 75 (MBC), indicating that it is in quite good shape.
3. Auction history: It has been auctioned 2 times in the past, of which it sold 1 time and did not sell 1 time. This suggests that there is interest in the coin, but also that there may be some resistance in the price.
4. Average hammer price: 100 euros, which is the average price it has sold for in the past.
5. Estimated price in previous auctions: In a previous auction, the estimated price was 70 euros, and the hammer price was 100 euros.

Given that the average hammer price is 100 euros and considering that the condition of the coin is good (75), a reasonable maximum purchase price could be in the range of the average hammer price.

Therefore, an estimated maximum purchase price could be 100 euros. However, since the starting price is 60 euros, buyers may be willing to pay a little more, but not necessarily up to the average hammer price. A range of 80 to 100 euros could be more realistic, depending on the competition in the auction.

In summary, an estimated maximum purchase price could be 100 euros, but with a more conservative approach, you might consider a range of 80 to 90 euros as a safer target.

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

1. Starting Price: 60 euros.
2. Condition: The coin is in a condition of 80 (VF+), indicating that it is in good shape.
3. Auction History: It has been auctioned 2 times in the past, of which it sold once and did not sell once. This suggests that there is interest in the coin, but also that there may be some resistance to paying more on certain occasions.
4. Average Hammer Price: 75 euros, which is the average price it has sold for in the past.
5. Previous Estimated Price: In the 2017 auction, the estimated price was 90 euros, and it hammered at 75 euros.

Given that the condition is good and the average hammer price is 75 euros, but there is also a previous estimated price of 90 euros, we could consider that the maximum purchase price could be in a range between these two values.

Taking into account the information and the interest in the coin, an estimated maximum purchase price could be approximately 85 euros. This falls between the average hammer price and the previous estimated price, reflecting a reasonable value for a buyer looking to secure the coin in good condition.

Based on the provided data, here is an analysis to estimate a maximum purchase price for the coin in question:

1. Starting Price: 80 euros. This is the initial price set for the auction.
2. Condition: The coin has a condition rating of 75 (MBC), indicating that it is in good shape, but not of the highest quality (FDC).
3. Auction History: The coin has been auctioned once in the past but did not sell, which may indicate that interest or demand is not high.
4. Average Hammer Price: There are no data on previous sales, making it difficult to establish a reference price based on past sales.

Given that the coin has a starting price of 80 euros and considering its condition (75), an estimated maximum purchase price could be slightly above the starting price, but not by much, since it has not been successful in previous sales.

Estimated Maximum Purchase Price: It may be reasonable to consider a maximum purchase price between 80 and 100 euros, depending on the interest of bidders in the auction. However, since it has not sold in the past, it is likely that the price will remain closer to the starting price. Therefore, a maximum purchase price of 90 euros could be a prudent estimate.

To estimate a maximum purchase price for the coin in question, we can 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. Auction History:
- The average hammer price in previous auctions is 1062.39 euros.
- It has been auctioned 39 times, of which 19 have been sold, indicating considerable interest in the coin.
- Previous hammer prices varied, but there are examples of auctions that have reached up to 3800 euros (in a condition of 90).

3. Starting Price and Average Starting Price:
- The current starting price is 100 euros, which is quite low compared to the average hammer price.
- The average starting price in the past has been 737.9 euros.

4. Price Trends:
- In previous auctions, prices have fluctuated considerably, but overall, hammer prices have been significantly higher than starting prices.

Given all this, and considering that the coin's condition is 70, an estimated maximum purchase price could be in the range of 800 to 1200 euros. This is based on the average hammer price and the demonstrated interest in previous auctions, as well as the current condition of the coin.

Therefore, an estimated maximum purchase price could be approximately 1200 euros.

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

1. Condition: The coin to be auctioned has a condition of 80 (MBC+). This is lower than the coins that have been sold in the past, which have a condition of 90. Generally, better condition translates to a higher price.

2. Previous auction prices: Previous auction prices for coins with a condition of 90 have been 600, 310, and 300 euros. This suggests that, under similar conditions, the auction price could be quite high.

3. Average auction price: The average auction price for this coin has been 403.33 euros, providing an additional reference.

4. Starting price: The starting price is 80 euros, indicating that the auction house expects moderate interest in the coin.

Given that the condition of the coin being auctioned is lower than those that have been sold previously, and considering the average auction price, an estimated maximum purchase price could be set at a lower range than the previous auction prices, but still, it could be attractive to a collector.

Taking all these factors into account, an estimated maximum purchase price could be around 250-300 euros. This is based on the current condition and historical interest in the coin, as well as the average auction price.

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

1. Starting Price: 80 euros.
2. Condition: The coin has a condition rating of 80 (MBC+), indicating that it is in quite good shape.
3. Auction History:
- It has been auctioned 11 times in the past, of which it has sold 7 times.
- The average hammer price in previous auctions is 57.86 euros, but there is a notable hammer price of 120 euros in a previous auction with a condition of 90.
- The last auction in 2022 had a hammer price of 70 euros with a condition of 85.

4. Price Trends:
- The current starting price is higher than the average starting price of 48.64 euros, suggesting that the seller has expectations of a higher price.
- The condition of 80 is better than most of the conditions of previously auctioned coins, which could justify a higher price.

Given that the coin is in good condition and considering the price history, an estimated maximum purchase price could be positioned between the starting price and the highest recorded hammer price.

Taking all this into account, an estimated maximum purchase price could be approximately 100 euros. This is based on the good condition and potential interest from collectors, as well as the highest hammer price observed in the past.

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 70 (VF-). This is an important factor, as coins in better condition tend to reach higher prices.

2. Auction History:
- In the past, this coin has been auctioned 4 times, of which it has sold 2 times. This indicates that there is interest in the coin, but also that there is a 50% no-sale rate, which may influence the perception of its value.
- Previous hammer prices are relevant. For example, in 2014, the coin sold for 124.81 euros, which is a considerably high price compared to the current starting price of 50 euros.

3. Average Hammer Price: The average hammer price of 89.9 euros is a good indicator of the value that buyers are willing to pay.

4. Starting Price: The starting price is 50 euros, which is relatively low compared to previous hammer prices.

5. Market Trends: Since there are no auctions scheduled in the coming days, this may increase competition among bidders interested in this coin.

Taking all these factors into account, an estimated maximum purchase price could be in a range between the average hammer price and the highest previous hammer price.

Therefore, an estimated maximum purchase price could be around 100 euros. This is based on the coin's condition, the demonstrated interest in previous auctions, and the average hammer price.

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

1. Condition: The coin has a condition of 70 (MBC-), which indicates that it is in relatively good shape, but not of the highest quality. This may influence its value.

2. Previous auction prices:
- In 2014, the coin was offered with a starting price of 1200 euros, but no final price was recorded, suggesting that it did not sell.
- In 2016, the starting price was 160 euros, with an estimated price of 200 euros and a final price of 450 euros. This indicates that, despite a lower starting price, the coin sold for a considerably higher price.

3. Average starting and final prices: The average starting price is 475 euros and the average final price is 450 euros. This suggests that, in general, coins of this reference tend to reach final prices close to these values.

4. Current auction situation: The coin has a starting price of 65 euros, which is significantly lower than previous starting prices. This could attract more bidders and potentially increase the final price.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 400 to 600 euros, considering that the condition is good and there is a history of final prices suggesting that the coin may reach a higher value in the current auction.

Therefore, a reasonable maximum purchase price could be approximately 500 euros.

1. Starting Price: 100 euros. This is the initial price set for the auction.
2. Condition: The coin has a condition rating of 70 (MBC-), indicating that it is in fairly good condition, but not of the highest quality (FDC).
3. Auction History: The coin has been auctioned once in the past but did not sell, which may indicate that interest or demand for this particular coin is not very high.
4. Average Hammer Price: There are no data on previous sales, making it difficult to establish an average hammer price.

Given that the coin has a condition rating of 70 and considering that it did not sell in the previous auction, it is likely that interest in the coin is not very high. However, since the starting price is 100 euros, we could estimate that the maximum purchase price might be in a range close to this price, but not necessarily reaching it.

Taking all these factors into account, an estimated maximum purchase price could be around 80-90 euros. This would allow a potential buyer to consider the condition and auction history without risking paying the full starting price, given that there is no guarantee that the coin will sell this time.
