To estimate a maximum purchase price for the coin in question, we can analyze the provided data and 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:
- In the past, the coin has been auctioned 7 times, of which it has sold 6 times. This suggests there is consistent interest in the coin.
- Previous hammer prices for coins with a similar condition (80) have been 1100 euros (2018) and 1600 euros (2013). This indicates that the hammer price can be quite high for coins in good condition.

3. Average Hammer Price: The average hammer price for this coin is 922 euros, which is also an important indicator to consider.

4. Starting Price: The current starting price is 300 euros, which is significantly lower than previous hammer prices.

5. Price Trends: Given that the average starting price is 433.33 euros and the average hammer price is 922 euros, there is a considerable margin between the starting price and the hammer price.

Based on these factors, an estimated maximum purchase price could be positioned in a range between the average hammer price and the higher hammer prices observed in the past.

Estimated Maximum Purchase Price:

We could consider a maximum purchase price of around 1100 to 1300 euros, as this range aligns with previous hammer prices for coins in similar conditions and the demonstrated interest in past auctions.

Therefore, a reasonable maximum purchase price could be 1200 euros.

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

1. Current starting price: 900 euros.
2. Coin condition: 80 (MBC+), indicating good preservation.
3. Auction history:
- It has been auctioned 6 times in the past, of which it has sold 4 times.
- The average starting price in previous auctions was 641.67 euros, and the average hammer price was 752.5 euros.
- Previous hammer prices varied, but the highest was 750 euros in 2014.

4. Previous hammer prices:
- 2018: Not sold (starting price 900, estimated 1500).
- 2014: Hammer price 750 (starting price 600, estimated 1000).
- 2013: Hammer price 460 (starting price 450, estimated 750).
- 2022: Hammer price 700 (starting price 600, estimated 1000).
- 2022: Not sold (starting price 400, estimated 650).

Given that the coin is in good condition (80) and considering the current starting price of 900 euros, which is higher than previous starting and hammer prices, it is reasonable to assume that interest in this coin could be greater in this auction.

However, it is also important to note that the average hammer price in the past has been lower than the current starting price. Therefore, an estimated maximum purchase price could be set in a range that reflects both the good condition and the price history.

Estimated maximum purchase price: It could be reasonable to consider a hammer price around 800-900 euros, given that the starting price is 900 euros and the hammer price history suggests that buyers might be willing to pay a little more, but not necessarily the full starting price.

Thus, an estimated maximum purchase price could be 850 euros.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially the previous auction prices and the current condition of the coin.

1. Current Condition: The coin has a condition of 75 (MBC), indicating that it is in an acceptable state, but not of the highest quality.

2. Previous Auction Prices: By observing the auction prices of coins with similar conditions (75 and 80), we can see that:
- In several auctions, coins with a condition of 75 have reached hammer prices ranging from 60 to 90 euros.
- Coins with a condition of 80 have achieved higher hammer prices, in the range of 90 to 140 euros.

3. Average Hammer Price: The average hammer price for this coin is 73.66 euros, which also provides us with a reference.

4. Starting Price: The starting price is 200 euros, which is significantly higher than the previous hammer prices for similar conditions.

Given that the condition of the coin is 75 and considering the previous hammer prices, an estimated maximum purchase price could be in the range of 80 to 100 euros. This is based on the fact that, although the starting price is high, the actual hammer price for similar conditions has been lower.

Therefore, a reasonable estimated maximum purchase price for this coin could be 100 euros.

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

1. Current condition: The coin has a condition rating of 30 (BC+), indicating that it is in a fairly deteriorated state. This will negatively affect its value compared to coins in better condition.

2. Auction history: The coin has been auctioned previously with an estimated price of 2000 euros and a hammer price of 1360 euros in a condition of 75. This suggests that the value could be significantly higher in better conditions.

3. Average hammer price: The average hammer price for this coin in the past has been 1080 euros, providing an additional reference point.

4. Starting price: The current starting price is 150 euros, indicating that the seller is looking for a low initial price, possibly to attract more bidders.

Given that the current condition is quite low (30), and considering the price history, a reasonable maximum purchase price could be in the range of 300 to 400 euros. This is based on the fact that, although the previous hammer price was 1360 euros, the current condition of the coin significantly limits its value.

Therefore, an estimated maximum purchase price could be 350 euros.

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

1. Starting price: 800 euros.
2. Average hammer price in the past: 1400 euros. This indicates that, although the starting price is 800 euros, the final price at which it has sold in the past is significantly higher.
3. Condition of the coin: 80 (MBC+). This suggests that the coin is in good condition, which may increase its value compared to coins in lower condition.
4. Auction history: The coin has been auctioned once and sold on that occasion, indicating that there is interest in it.

Given that the average hammer price is 1400 euros and considering that the condition is good, an estimated maximum purchase price could be in a range between the starting price and the average hammer price.

Taking these factors into account, an estimated maximum purchase price could be around 1200 to 1300 euros. This reflects an interest in the coin, but also a margin of safety in case the demand is not as high as in the previous auction.

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

1. Starting Price: 3000 euros.
2. Condition: The coin has a condition of 80 (MS+), indicating that it is in quite good shape.
3. Historical Data:
- In December 2018, a coin with a condition of 75 was auctioned with a starting price of 4000 euros and sold for 6000 euros.
- In March 2018, another coin with the same condition of 75 had a starting price of 1500 euros and sold for 3800 euros.

4. Average Hammer Price: 4533.33 euros, indicating that, in general, coins of this reference tend to sell above their starting price.

Given that the condition of the coin in question is better (80) than the previous ones (75), it is reasonable to assume that its hammer price could be higher than the previous examples.

### Estimation of the Maximum Purchase Price:
- Considering the average hammer price (4533.33 euros) and the fact that the condition is better, we could estimate that the hammer price could be in a higher range.
- A conservative approach could be to add 10-20% to the average hammer price, given the state of preservation.

Therefore, an estimated maximum purchase price could be in the range of 5000 to 5500 euros. This is based on the trend of previous prices and the better condition of the current coin.

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

1. Current starting price: 3000 euros.
2. Auction history:
- In 2018, the coin was auctioned with a starting price of 2500 euros and sold for 5000 euros, with a grade of 85.
- In 2019, it was auctioned with a starting price of 900 euros and sold for 1050 euros, with a grade of 50.

3. Average hammer price: 4100 euros, indicating that, in general, coins of this reference tend to sell for a price higher than the starting price.

4. Condition: There is no information about the condition of the current coin, which may influence its value. However, the hammer price of the coin with a grade of 85 (5000 euros) suggests that good condition can significantly increase the price.

Given that the starting price is 3000 euros and considering the auction price history, an estimated maximum purchase price could be between the average hammer price (4100 euros) and the highest hammer price (5000 euros) from the previous auction.

Therefore, an estimated maximum purchase price could be approximately 4500 euros. This reflects a balance between the current starting price and the potential hammer price based on previous auctions.

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

1. Current starting price: 2000 euros.
2. Condition of the coin: 85 (MBC+/EBC-), which indicates good preservation.
3. Auction history: The coin has been auctioned 3 times in the past, and it has sold every time. This indicates a consistent interest in the coin.
4. Previous hammer prices: In past auctions, the hammer prices were 6500 euros and 7000 euros, both with similar preservation (85).
5. Average hammer price: 6100 euros, which is a good indicator of market value.

Given that the current starting price is significantly lower than the previous hammer prices, and considering that the condition is good, it can be estimated that the maximum purchase price could be in a higher range.

Taking all these factors into account, an estimated maximum purchase price could be between 6000 and 7000 euros, aligning with previous hammer prices. However, since the starting price is 2000 euros, there is likely to be competition in the auction, which could drive the final price up.

Therefore, a reasonable estimated maximum purchase price could be 7000 euros.

- The average hammer price for this coin in previous auctions is 2943.75 euros.
- In the 2022 auction, the coin sold for 7500 euros with a condition rating of 95, indicating that coins in better condition can reach significantly higher prices.
- In the 2024 auction, the same coin was hammered at 3000 euros with a condition rating of 80, which is relevant for our estimation.

3. Starting Price and Average Starting Price:
- The current starting price is 1500 euros, which is below the average starting price of 1661.11 euros. This suggests that the starting price is reasonable and could attract more bidders.

4. Sales Trends: The coin has been auctioned 9 times, of which it has sold 8 times. This indicates a consistent interest in the coin, which may influence the hammer price.

Based on these factors, an estimated maximum purchase price could be in the range of 2500 to 3000 euros, considering that the condition is 80 and that in previous auctions it has reached hammer prices of up to 3000 euros under similar conditions.

Therefore, a reasonable maximum purchase price could be approximately 2800 euros.

- A coin with a condition of 90 sold for 3000 euros in 2018.
- Another with a condition of 95 sold for 12600 euros in 2019, although this is an exceptional case.

3. Average Hammer Price: The average hammer price for similar coins is 2737.92 euros, suggesting that the market is willing to pay more than the current starting price.

4. Auction Trends: The coin has been auctioned 14 times, with an 85.7% sell-through rate (12 out of 14). This indicates a consistent interest in the coin.

5. Comparison with Previous Starting and Hammer Prices: Most coins with conditions ranging from 80 to 90 have had hammer prices ranging from 1200 to 3000 euros.

Based on these factors, an estimated maximum purchase price could be around 3000 euros, as this price reflects both the condition of the coin and the market interest in previous auctions. However, it is important to keep in mind that the final price will depend on the competition in the auction and the demand at that specific moment.
