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+), which indicates that it is in relatively good shape, although not the best possible condition.

2. Auction History:
- The average hammer price in previous auctions is 90.88 euros.
- In past auctions, hammer prices have varied significantly, with some reaching up to 250 euros in similar conditions (condition of 95).
- The last auction with a condition of 80 had an estimated price of 20 euros, but the hammer price is not available.

3. Starting Price and Average Starting Price:
- The current starting price is 12 euros, which is quite low compared to the average starting price of 70.44 euros.

4. Sales Trends: Of the 32 times it has been auctioned, it has sold 19 times, indicating a reasonable sales rate.

Based on these factors, an estimated maximum purchase price could be in the range of 80 to 120 euros, considering that the condition is good and that the hammer price history suggests it could reach higher figures in auctions. However, since the starting price is low, it could be a good opportunity to acquire it at a more accessible price.

Therefore, a reasonable maximum purchase price could be 100 euros.

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 90 (EF), which indicates that it is in good shape. This generally increases its value compared to coins in lower conditions.

2. Auction History:
- The average hammer price for similar coins in condition 90 has been between 18 and 34 euros in previous auctions.
- In past auctions, coins with condition 90 have sold for prices ranging from 18 to 34 euros, with a starting price of 18 euros in a recent auction.

3. Average Starting and Hammer Price:
- The average starting price is 31.16 euros and the average hammer price is 33.86 euros. This suggests that the market is willing to pay close to these values.

4. Price Trends:
- In previous auctions, the hammer price has varied, but coins in similar conditions have reached prices of up to 90 euros in the past, although this may be an exceptional case.

Based on this data, an estimated maximum purchase price for the coin in condition 90 could be in the range of 35 to 50 euros, considering that the average hammer price is 33.86 euros and that the condition is good. However, since the starting price is 15 euros, it is likely that the final price will not significantly exceed this range.

Therefore, a reasonable estimated maximum purchase price could be 45 euros.

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 85 (ebc-), which indicates 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 for coins with similar conditions, we can see that:
- In recent auctions, coins with a condition of 85 have reached hammer prices of up to 20 euros.
- In earlier auctions, coins with conditions of 90 and 95 have reached hammer prices of 40 to 80 euros.

5. Sales Trends: The coin has been auctioned 44 times, of which 29 have resulted in sales. This indicates a consistent interest in the coin, which may influence its price.

Taking all these factors into account, an estimated maximum purchase price for this coin, considering its condition and previous hammer prices, could be in the range of 20 to 40 euros. This is based on the fact that coins with a similar condition have reached hammer prices in that range in the past. However, given the interest in the coin and its condition, a reasonable maximum purchase price could be 30 euros.

3. Starting Price and Average Starting Price:
- The current starting price is 110 euros, which is a good starting point.
- The average starting price of 77.57 euros suggests that, in general, coins of this reference tend to start at lower prices, but this may not reflect the actual value of the coin in good condition.

4. Recent Trends: In the most recent auction, a coin with a condition of 100 sold for 950 euros, indicating that there is a strong market for high-quality coins.

Based on these factors, an estimated maximum purchase price for the coin in condition 90 could be between 200 and 300 euros, considering that the average hammer price is 151.54 euros and there is potential for an increase due to the good condition and market demand.

Therefore, a reasonable maximum purchase price could be 250 euros.

Estimated maximum purchase price: 100 euros.

This price reflects a balance between the current condition and the hammer price history, taking into account that there may be competing bidders interested in the auction.

4. Auction Trends: Since the coin has been sold on all previous occasions and there have been no failed attempts at sale, this indicates a steady demand.

Based on these factors, an estimated maximum purchase price could be in the range of 40 to 60 euros, considering that the average hammer price is 39.4 euros and that the coin's condition is high. However, taking into account the exceptional hammer price of 130 euros in 2018, it might be reasonable to consider a maximum price of up to 70 euros, depending on the competition in the auction and the interest of collectors.
