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 suggests that its value should be in a medium-high range.

2. Previous Prices: Looking at previous auction prices for coins with a similar condition (75), the highest auction price was 80 euros in 2020. However, there are also more recent auctions showing higher prices, such as 130 euros in 2021 for a coin with a condition of 80.

3. Average Auction Price: The average auction price for this coin is 105.72 euros, indicating that, in general, coins of this reference tend to sell for relatively high prices.

4. Recent Trends: In the most recent auctions, the hammer prices have shown an increase, with auctions of 140 euros and 210 euros for coins of similar condition.

5. Starting Price: The starting price is 45 euros, which is relatively low compared to previous hammer prices.

Taking all these factors into account, an estimated maximum purchase price for this coin could be in the range of 120 to 150 euros, considering that the condition is good and there is an upward trend in auction prices in recent sales.

Therefore, a reasonable estimated maximum purchase price could be 130 euros.

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

1. Coin Condition: The coin has a condition rating of 80 (MS+), 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 is 242.21 euros.
- In previous auctions, hammer prices have varied significantly, but some relevant examples are:
- In 2020, a coin with a similar condition (80) was sold for 65 euros.
- In 2018, another coin with a condition of 80 sold for 40 euros.
- In 2023, a coin with a condition of 80 was auctioned for 75 euros.

3. Starting Price and Recent Hammer Prices:
- The current starting price is 30 euros, which is relatively low compared to the average hammer price.
- Given that the average hammer price is significantly higher than the starting price, this suggests there is potential for the coin to sell for a higher price.

4. Auction Trends: The coin has been auctioned 77 times, with a high sales percentage (71 out of 77). This indicates a consistent interest in this coin, which may influence the price.

Based on these factors, an estimated maximum purchase price could be in the range of 200 to 300 euros, considering that the average hammer price is 242.21 euros and that the coin's condition is good. However, given the hammer price history, a more conservative price might be around 200 euros, while a more optimistic price could reach up to 300 euros if there is active competition in the auction.

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 relatively good shape. This generally translates to a higher price compared to coins in lower conditions.

2. Auction History:
- The average hammer price in previous auctions is 95.25 euros, suggesting that, on average, coins of this reference sell for a price close to this value.
- The last auction with a known hammer price was 140 euros (in 2016), indicating that there is potential to reach higher prices depending on demand.

3. Starting Price and Previous Sales:
- The current starting price is 50 euros, which is relatively low compared to the average hammer price. This may attract more bidders and potentially raise the final price.
- There have been 12 previous auctions, of which 9 resulted in sales, indicating a consistent interest in this coin.

4. Price Trends:
- Observing previous hammer prices, there is a trend for coins in good condition (like the current one) to sell above the starting price.

Based on these factors, an estimated maximum purchase price could be in the range of 100 to 120 euros. This is based on the average hammer price and the price history of similar coins in comparable conditions.

Therefore, a reasonable maximum purchase price could be 110 euros.

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

### Final Estimation
Taking all these factors into account, an estimated maximum purchase price for this coin could be between 120 and 150 euros. This is based on the hammer price history for coins with similar conditions and the current market context.

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 (VF), which indicates that it is in acceptable shape, but not among the best qualities. This can influence the price, as coins in better condition tend to fetch higher prices.

2. Auction History:
- The average hammer price for similar coins is 181.63 euros.
- In the past, coins of the same reference with similar conditions have sold for prices that varied significantly, from 35 euros to 440 euros, depending on the condition and demand at that time.

3. Starting and Hammer Price:
- The current starting price is 60 euros, which is relatively low compared to the average hammer price.
- The last auction of a similar coin with a condition of 80 had a hammer price of 140 euros, suggesting there is potential for price increase.

4. Sales Trends: Of the 14 times it has been auctioned, 13 have sold, indicating good demand for this coin.

Based on these factors, an estimated maximum purchase price could be in the range of 150 to 200 euros, considering that the condition is slightly lower than that of coins that have reached higher prices in the past. This also takes into account the average hammer price and sales trend.

Therefore, a reasonable maximum purchase price could be 180 euros.
