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 a medium-low quality. This may influence the price, as coins in better condition tend to fetch higher prices.

2. Starting Price and Average Hammer Price: The starting price is 40 euros, and the average hammer price in previous auctions is 81.9 euros. This suggests that, generally, coins of this reference tend to sell for a price higher than the starting price.

3. Sales History: The coin has been auctioned 29 times, of which it has sold 21 times. This indicates good demand, which may drive up the price.

4. Previous Prices: Looking at previous hammer prices, there are examples of similar coins that have sold for prices that varied significantly, from 28.88 euros to 406.71 euros, depending on the condition and other factors.

5. Recent Trends: In the most recent auctions, the hammer prices have shown a range that suggests that, although condition is a factor, there is sustained interest in this coin.

Given all this, an estimated maximum purchase price could be set in a range between 80 and 100 euros, considering that the average hammer price is 81.9 euros and that the condition of 75 may limit the price compared to coins in better condition.

Therefore, a reasonable maximum purchase price could be 90 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 75 (VF), indicating that it is in fairly good shape, but not among the highest qualities.

2. Auction History:
- The average hammer price in previous auctions is 83.34 euros.
- It has been auctioned 18 times, of which 14 have sold, indicating good demand.
- Previous hammer prices varied, but there are examples of hammer prices exceeding 100 euros, such as in 2023 where it sold for 91 euros and in 2016 where it sold for 112.05 euros.

3. Starting Price: The starting price is 40 euros, which is relatively low compared to previous hammer prices.

4. Price Trends: The average starting price in previous auctions is 66.81 euros, suggesting that buyers are willing to pay more than the starting price.

5. Future Projections: In the upcoming auction, the estimated price is 160 euros, indicating expectations that the value of the coin may increase.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 90 to 120 euros. This is based on the history of hammer prices and the current condition of the coin. A price of 100 euros could be a reasonable target, as it falls in the middle of this range and aligns with buyer expectations 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 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. Current Starting Price and Previous Prices: The current starting price is 60 euros, and the average starting price in previous auctions is 103.65 euros. This suggests that the current starting price is relatively low compared to the historical average.

3. Previous Hammer Prices: The average hammer price in previous auctions is 164.23 euros. This indicates that, in general, coins of this reference tend to sell for significantly higher prices than their starting price.

4. Historical Data: Looking at previous hammer prices, there are examples of similar coins that have sold for prices that vary considerably, but many of them exceed 100 euros, even reaching up to 325 euros in some cases.

5. Demand and Supply: Since there are no auctions scheduled in the coming days, this could increase the demand for the current coin, potentially leading to a higher hammer price.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 150 to 200 euros, considering that the condition is good and that the historical hammer price suggests that buyers are willing to pay more for coins in similar conditions.

Therefore, a reasonable maximum purchase price could be 180 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 80 (VF+), which indicates that it is in relatively good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Auction History:
- The average hammer price in previous auctions is 35.38 euros.
- The average starting price is 36.73 euros.
- 37 out of the 69 coins auctioned have been sold, indicating a sell-through rate of 53.6%.

3. Previous Prices:
- In past auctions, hammer prices have varied significantly, with some reaching up to 110 euros in exceptional conditions (such as in 2022 with a condition of 95).
- The majority of hammer prices for similar conditions (75-85) have been in the range of 20 to 60 euros.

4. Recent Trends:
- In the most recent auctions, hammer prices have been in the range of 30 to 50 euros for similar conditions.

Based on these factors, an estimated maximum purchase price for the coin with a condition of 80 (VF+) could be in the range of 50 to 70 euros. This is based on the hammer price history and the current condition, which suggests that the coin has significant value but does not reach the highest levels of condition.

Therefore, a reasonable maximum purchase price could be 65 euros.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, especially the hammer prices and the conditions of similar coins in previous auctions.

1. Condition of the current coin: 80 (MBC+).

3. Price analysis:
- The average hammer price for coins with a condition of 80 seems to be in the range of €35 to €45.
- The average starting price is €29.15, indicating that the market is willing to start bidding in that range.

4. Estimation:
- Given that the condition of the coin is 80 and considering previous hammer prices, a reasonable maximum purchase price could be in the range of €45 to €50.

Therefore, an estimated maximum purchase price for this coin could be €45.

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

1. Condition: The coin has a condition rating of 85 (ebc-), which is quite good. In the past, coins with this condition have reached auction prices of up to 232.93 euros.

Taking all these factors into account, an estimated maximum purchase price could be in the range of 200 to 250 euros, considering that the highest auction price in the past was 232.93 euros and that the current condition is favorable. Therefore, a reasonable maximum purchase price could be approximately 220 euros.
