To estimate a maximum purchase price for the coin in question, we will 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 of the best quality (FDC).

2. Auction History:
- It has been auctioned 9 times, of which it has sold 7 times. This indicates good demand.
- The average hammer price in previous auctions is 90.43 euros, suggesting that, in general, buyers are willing to pay close to this price.

3. Previous Prices:
- In the 2023 auction, the coin was estimated at 180 euros and sold for 290 euros, indicating a potential for high demand and that prices can vary significantly.
- In other auctions, hammer prices have ranged from 13 to 290 euros, depending on the condition and other factors.

4. Starting Price: The starting price is 25 euros, which is relatively low compared to the average hammer price.

Given that the coin's condition is 75 and considering the price history, an estimated maximum purchase price could be positioned in a range between the average hammer price and the highest recorded price.

Taking all these factors into account, an estimated maximum purchase price could be around 120-150 euros. This is based on the good condition of the coin and the interest shown in previous auctions.

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 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 coins with a similar condition (80) in the past has been approximately 35-50 euros.
- In previous auctions, coins with a condition of 80 have reached hammer prices of up to 35 euros (as in the auction on 2020-02-13) and 50 euros (as in the auction on 2022-04-28).

3. Starting Price and Average Starting Price:
- The current starting price is 25 euros, which is below the average starting price of 34.57 euros. This suggests that there is potential for the hammer price to be higher.

4. Sales Trends: The coin has been sold in 35 out of 47 auctions, indicating good demand.

5. Comparison with Previous Prices: In previous auctions, the highest hammer price for coins with a similar condition has been 110 euros (although this was for a condition of 85).

Based on these factors, an estimated maximum purchase price for this coin could be between 50 and 70 euros, considering that the condition is good and the price history suggests it could reach a higher price at auction.

Therefore, a reasonable maximum purchase price could be 70 euros.

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 70 (VF-), indicating that it is in acceptable condition, but not among the best. This may influence the price, as coins in better condition tend to fetch higher prices.

- The average hammer price in previous auctions is 69.47 euros.
- The coin has been auctioned 19 times, of which it has sold 15 times. This indicates good demand.
- In previous auctions, hammer prices have varied, but there are examples of hammer prices exceeding 80 euros, especially for coins in better condition.

3. Starting Price and Average Starting Price:
- The current starting price is 25 euros, which is relatively low compared to the average starting price of 47.44 euros.

4. Price Trends:
- In recent auctions, the hammer price has reached up to 160 euros for coins in better condition. However, for a coin with a condition rating of 70, it is reasonable to expect a lower price.

Taking all these factors into account, an estimated maximum purchase price for this coin could be between 70 and 90 euros. This is based on the auction price history and the current condition of the coin. A price of 80 euros could be a reasonable target, given that it is in acceptable condition and there is demand in the market.

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

1. Current Condition: The coin has a condition of 75 (MBC), which indicates that it is in a medium-low state. This generally affects the price, as coins in better condition tend to reach higher prices.

2. Auction History:
- The average hammer price in previous auctions is 87.58 euros.
- The condition of the coins auctioned in the past varies, but there are examples of coins with similar conditions that have sold for prices ranging from 20 to 240 euros, depending on the condition and demand at that time.

3. Starting Price: The current starting price is 15 euros, which is relatively low compared to the average hammer price.

4. Price Trends: Observing the hammer prices of coins with similar conditions, it seems that the price range can vary quite a bit. For example, coins with conditions from 70 to 80 have reached hammer prices between 20 and 50 euros on several occasions.

5. Supply and Demand: Since there are no auctions scheduled in the coming days, this could influence demand and, therefore, the price.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 40 to 60 euros. This is based on the historical hammer prices of coins with similar conditions and the average hammer price observed. However, it is important to note that the final price may vary depending on the competition in the auction and the specific demand at that time.

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 70 (VF-), indicating that it is in relatively good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History: The coin has been auctioned 12 times in the past, with 8 successful sales. This suggests that there is consistent interest in the coin. The average hammer price in previous auctions is 96 euros, providing a good benchmark.

3. Previous Starting and Hammer Prices: By observing the starting and hammer prices from previous auctions, we note that the hammer price has varied, but generally, coins with similar conditions have reached hammer prices ranging from 60 to 200 euros, depending on the condition and demand at that time.

4. Current Starting Price: The starting price is 50 euros, which is relatively low compared to the previous average hammer price.

5. Price Trends: In the most recent auction, the coin sold for 50 euros, indicating that interest may have decreased, but it could also be an opportunity to acquire it at a lower price.

Taking all these factors into account, an estimated maximum purchase price could be around 100-120 euros, given that the condition is good and the price history suggests it could reach that range in a competitive auction. However, it is important to pay attention to demand at the time of the auction, as this can influence the final price.

Therefore, a reasonable estimated maximum purchase price would be 85 euros.

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 20 (BC-), indicating that it is in quite low condition. This generally negatively affects the hammer price.

2. Auction History:

Therefore, an estimated maximum purchase price could be:

Estimated maximum purchase price: 300 euros.

This price reflects both the condition value and the price trend in previous auctions.

### Analysis

- The current condition of the coin (75) is lower than the conditions of the coins auctioned in 2021 (80) and 2022 (85), suggesting that its value may be lower than the selling prices of those auctions.
- However, the selling price of 1950 euros in 2015 is a significant data point, although the condition of that coin is not specified.
- The average selling price of 870 euros indicates that, in general, coins of this reference tend to sell for higher prices than the current starting price.

### Estimation
