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 85 (ebc-), which is relatively high and may positively influence its value.

2. Previous Prices: By observing previous auction prices, we can see that in recent auctions, coins with similar conditions have reached hammer prices of up to 1400 euros (as seen in the auction on April 27, 2022).

3. Starting Price and Average Hammer Price: The current starting price is 900 euros, and the average hammer price in previous auctions is 656.31 euros. This suggests that the starting price is higher than the average hammer price, which could indicate an expectation of greater interest in this auction.

4. Sales Trends: The coin has been auctioned 23 times, of which it has sold 16 times. This indicates a reasonable sales rate, which can be a good indicator of demand.

5. Previous Estimates: Estimated prices in previous auctions have varied, but have reached up to 2000 euros on some occasions, suggesting there is potential for a high hammer price.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 1200 to 1500 euros, considering the current condition and previous hammer prices. This would allow for a competitive bid without exceeding the market value observed in past auctions.

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 rating of 80 (VF+). This is an important factor, as coins in better condition tend to fetch higher prices.

2. Previous Auction Prices:
- In previous auctions, we have seen hammer prices that vary significantly. For example:
- In 2018, a coin with a condition of 95 sold for 2200 euros.
- In 2022, a coin with a condition of 95 sold for 2600 euros.
- In 2023, a coin with a condition of 90 sold for 950 euros.
- In 2020, a coin with a condition of 80 sold for 460 euros.

3. Price Trends:
- The average hammer price for this coin is 1041.22 euros, indicating that, in general, coins of this reference tend to sell for above 1000 euros, especially if they are in better condition.
- The condition of 80 has shown hammer prices ranging between 400 and 460 euros in previous auctions.

4. Starting Price: The starting price is 400 euros, which is a reasonable starting point.

5. Estimation: Given that the condition is 80 and considering the previous hammer prices, a maximum purchase price could be in the range of 600 to 800 euros. This is based on the fact that, although the condition is not the highest, there is interest in the coin, and the average hammer price suggests it could reach a higher value.

Therefore, an estimated maximum purchase price for this coin could be approximately 700 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+), indicating that it is in quite good shape. This generally translates to a higher price compared to coins in lower conditions.

2. Auction History:
- The average hammer price for similar coins in the past is 104.95 euros.
- Previous auctions of this coin have shown hammer prices that vary, but there are examples of sales reaching up to 370 euros for coins in similar or better conditions.

5. Comparison with Previous Prices:
- In previous auctions, coins with a condition rating of 80 have reached hammer prices that vary, but some examples show sales from 90 to 370 euros.

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 that the hammer price history suggests potential for reaching higher prices at auctions. However, since the market can be volatile, it is advisable to keep an eye on the competition in the auction and adjust the bid accordingly.

Given that the coin has a conservation rating 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 previous auctions, the average hammer price is 0, which suggests that there is no historical data that could influence the estimation. However, since the conservation is good and there is interest in the auction, we could estimate a hammer price that might be slightly higher than the starting price.

Taking these factors into account, an estimated maximum purchase price could range between 400 and 500 euros, depending on the interest of collectors and the competition in the auction.

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.

- 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.

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:

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.
