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 translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The average hammer price for similar coins in condition 75 has been 65 euros in recent auctions.
- In the past, coins with a condition of 75 have sold for varying prices, but the highest recorded hammer price for a coin of similar condition was 180 euros (although this coin had a condition of 90).

3. Starting Price and Average Starting Price: The current starting price is 25 euros, and the average starting price for similar coins is 57.65 euros. This suggests that the starting price is relatively low compared to the market value.

4. Sales Trends: Out of the 21 times this coin has been auctioned, it has sold 14 times, indicating good demand.

Based on these factors, an estimated maximum purchase price could be in the range of 70 to 90 euros, considering that the average hammer price for coins of similar condition is 65 euros and that the starting price is low. This also takes into account the possibility that collector interest could drive the price up at auction.

Therefore, a reasonable estimated maximum purchase price would be 80 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 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 past auction prices, we can see that there is considerable variability. For example, in previous auctions, coins with similar conditions have reached hammer prices ranging from 20 to 500 euros, depending on demand and other factors.

3. Average Hammer Price: The average hammer price for this coin is 85 euros, which can serve as a good reference point.

4. Starting Price: The current starting price is 25 euros, suggesting that there is considerable room for the hammer price to be higher.

5. Sales Trends: The coin has been auctioned 42 times, of which 36 have been sold, indicating a good sales rate and sustained interest in this coin.

Based on these factors, an estimated maximum purchase price could be in the range of 100 to 150 euros, considering that the condition is good and that interest in the coin appears to be solid. 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.

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 with lower conditions.

2. Auction History:
- The average hammer price for this coin in the past is 36.22 euros.
- Previous hammer prices have varied, but there are examples of hammer prices of 75 euros (in 2020) and 50 euros (in 2021) for coins of similar or lower condition.

3. Starting Price: The current starting price is 30 euros, which is a good starting point. However, since the average hammer price is higher, it is reasonable to expect that the final hammer price will be higher.

4. Sales Trends: The coin has been auctioned 12 times, of which it has sold 10 times. This indicates good demand and sustained interest in the coin.

5. Comparison with Previous Prices: Looking at previous hammer prices, the highest was 75 euros, and the lowest was 16 euros. However, given that the current condition is 80, it is likely that the hammer price will be closer to the upper range.

Based on these factors, an estimated maximum purchase price could be between 50 and 75 euros. Given that the average hammer price is 36.22 euros and considering the condition, a reasonable maximum price could be approximately 60 euros. This allows for some margin for competition in the auction and reflects the historical interest in the coin.

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 75 (VF), which is quite good, but not the best. This can influence the price, as coins in better condition tend to reach higher prices.

2. Auction History:
- In 2022, the coin was auctioned with a starting price of 250 euros and sold for 200 euros, indicating that interest in that auction was moderate.
- In 2024, the same coin with a condition of 80 (better than the current one) had a starting price of 200 euros and sold for 480 euros, showing that there is potential for price increase depending on the condition.

3. Average Hammer Price: The average hammer price for similar coins is 320 euros, which can serve as a reference for establishing a maximum price.

4. Current Starting Price: The starting price is 150 euros, suggesting that the seller is initially looking for a lower price, but this does not necessarily reflect the true value of the coin.

Taking these factors into account, an estimated maximum purchase price could be positioned between the average hammer price and the highest observed hammer price. Given that the current condition is 75, and considering the average hammer price of 320 euros, a reasonable maximum price could be:

Estimated Maximum Purchase Price: 300 euros.

This price reflects a balance between the current condition and historical interest in the coin.

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 75 (MBC), which indicates that it is in fairly good shape, but not the best possible condition.

2. Auction History:
- The average hammer price for similar coins has been 197.22 euros.
- In previous auctions, we have seen hammer prices that varied, but some relevant examples are:
- In 2022, a coin with a condition of 80 sold for 650 euros.
- In 2024, a coin with a condition of 85 sold for 240 euros.
- In 2022, a coin with a condition of 70 sold for 70 euros.

3. Starting Price and Average Starting Price:
- The current starting price is 30 euros, and the average starting price has been 146.94 euros.

4. Price Trends:
- Given that the coin has a history of hammer prices that can be significantly higher than the starting price, it is reasonable to assume that the hammer price could be considerably greater.

Based on these factors, an estimated maximum purchase price could be in the range of 200 to 300 euros, considering that the condition is good and that the price history shows that similar coins have reached higher prices in previous auctions.

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

To estimate a maximum purchase price for the coin that will be auctioned, we will consider several factors, including the starting price, the condition of the coin, and the hammer prices from previous auctions of coins with similar conditions.

3. Price Trend: The hammer prices for coins in similar conditions have shown a range that can be considerably higher than the starting price.

### Estimation of Maximum Purchase Price:
Given that the highest hammer price for a similar condition has been 70 euros, and considering that the starting price is 30 euros, a reasonable maximum purchase price could be slightly higher than the highest observed hammer price.

Estimated Maximum Purchase Price: 70 - 80 euros.

This range allows for competitive bidding in the auction without exceeding the historical hammer prices for coins in similar conditions.

To estimate a maximum purchase price for the coin that is going to be auctioned, we can consider several factors, including the coin's condition, previous auction prices, and the average auction price.

1. Coin Condition: The coin in question has a condition rating of 80 (VF+). This indicates that it is in relatively good shape, which can positively influence its price.
