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 fairly good shape, but not the best possible condition.

2. Auction History:
- The average hammer price for similar coins has been 247.38 euros.
- In previous auctions, coins with similar conditions (70-80) have reached hammer prices that varied, but some examples are:
- 90 euros (condition 70)
- 150 euros (condition 70)
- 240 euros (condition 85)
- 211 euros (condition 80)
- 180 euros (condition 85)

3. Starting Price and Average Starting Price:
- The current starting price is 100 euros, and the average starting price in the past has been 136.22 euros.

4. Price Trends:
- The general trend seems to be that coins with a condition of 75 can reach hammer prices ranging between 150 and 200 euros, based on auction history.

Based on these factors, an estimated maximum purchase price for the coin could be between 180 and 220 euros, considering that the condition is good and that the hammer price history for similar coins supports this estimate.

Therefore, a reasonable maximum purchase price could be 200 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 of 70 (VF-). This indicates that it is in an acceptable state, but not of the highest quality.

2. Starting Price and Average Hammer Price: The starting price is 400 euros, and the average hammer price in previous auctions is 282.81 euros. This suggests that the starting price is relatively high compared to what has been sold in the past.

3. Sales History: The coin has been auctioned 99 times, of which it has sold 92 times. This indicates good demand and a history of successful sales.

4. Previous Prices: Looking at previous hammer prices for coins with similar conditions (70-80), prices have varied, but many have been in the range of 220 to 400 euros. The last auction with a similar condition (70) had a hammer price of 231 euros.

5. Recent Trends: In the most recent auctions, hammer prices have been in a higher range, with some reaching up to 600 euros for higher conditions.

Given all this, an estimated maximum purchase price could be set in a range between 350 and 450 euros, considering that the starting price is 400 euros and that the condition is 70. This allows for some competition in the auction but also reflects the hammer price history for similar conditions.

Therefore, a reasonable maximum purchase price could be 450 euros.

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 90 (EF), which indicates that it is in good shape. This generally translates to a higher price compared to coins with lower conditions.

2. Previous Prices: By looking at previous auction prices for coins with a similar condition (90 or close), we can see that:
- In the auction on 2020-07-02, a coin with a condition of 90 was sold for 380 euros.
- In the auction on 2018-10-17, another coin with a condition of 90 was sold for 300 euros.
- In the most recent auction (2023-01-31), it was sold for 460 euros.

3. Starting Price and Average Hammer Price: The current starting price is 460 euros, and the average hammer price in the past has been 335.83 euros. However, the most recent high hammer price (460 euros) suggests that there is significant interest in this coin.

4. Market Trends: Given that the coin has been auctioned 38 times and has had a sell-through rate of 97.37% (37 out of 38), this indicates a steady demand.

Based on these factors, an estimated maximum purchase price could be in the range of 460 to 500 euros, considering that interest in the coin seems to be increasing and that the most recent high hammer price has reached 460 euros.

Therefore, a reasonable maximum purchase price could be 500 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 85 (ebc-), indicating that it is in fairly good shape, but not the best possible condition.

2. Historical Prices: By looking at previous auction prices for coins with a similar condition (85), we can see that the hammer prices have varied, but generally, they have been in a range of 300 to 420 euros.

3. Starting Price and Average Hammer Price: The current starting price is 460 euros, which is higher than the average hammer price of 310.78 euros. This suggests that the seller has high expectations, but it may also indicate that the market is willing to pay more for this particular coin.

4. Recent Trends: In the most recent auctions, hammer prices for coins of similar condition have been in the range of 360 to 440 euros.

Based on these factors, an estimated maximum purchase price could be around 400-450 euros. This is based on the fact that, although the starting price is 460 euros, the price history suggests that a more realistic hammer price for a coin in this condition could be slightly lower.

Therefore, a reasonable maximum purchase price could be 450 euros.

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

1. Current Condition: The coin has a condition rating of 80 (MS+). This is an important factor, as coins in better condition tend to reach higher prices.

2. Starting Price: The starting price is 460 euros. This is the starting point for the auction.

3. Sales History: By observing the hammer prices of coins with similar conditions in the past, we can see that the hammer prices have varied. For example, in previous auctions, coins with conditions ranging from 75 to 90 have had hammer prices ranging from 260 to 400 euros, depending on demand and other factors.

4. Recent Trends: In the most recent auctions, hammer prices for coins with conditions of 85 to 90 have been around 360 to 450 euros. This suggests that there is growing interest in coins of similar quality.

5. Average Hammer Price: The average hammer price for this coin is 299.08 euros, indicating that, in general, buyers are willing to pay around this amount.

Given all this, an estimated maximum purchase price for this coin could be in the range of 400 to 500 euros, considering that the condition is good and the starting price is 460 euros. However, since the starting price is already relatively high, it is likely that the hammer price will not exceed 500 euros unless there is strong competition in the auction.

Therefore, a reasonable maximum purchase price could be 450 euros.

To estimate a maximum purchase price for the coin with a grade of 85 (ebc-), we can analyze historical data from previous auctions of coins with a similar grade.

1. Relevant data from previous auctions:
- In the past, coins with a grade of 85 have had hammer prices that varied, but we can observe some examples:
- 2020-11-10: Hammer price of 340 with a grade of 85.
- 2020-10-20: Hammer price of 326 with a grade of 85.
- 2020-07-02: Hammer price of 320 with a grade of 85.
- 2020-05-26: Hammer price of 314 with a grade of 85.

2. Price analysis:
- The hammer prices for coins with a grade of 85 have been in a range of approximately 314 to 340 euros.
- The average hammer price for coins with a grade of 85 seems to be around 320 euros.

3. Additional considerations:
- The current starting price is 460 euros, which is significantly higher than the previous hammer prices for similar grades.
- Since the starting price is higher than historical prices, it is possible that the demand or rarity of this particular coin justifies a higher price.

4. Estimation of the maximum purchase price:
- Based on historical data and the starting price, a reasonable maximum purchase price could be in the range of 340 to 360 euros, considering that the starting price is higher and there may be interest in the coin.

Therefore, an estimated maximum purchase price for this coin could be 360 euros.

To estimate a maximum purchase price for the coin in question, let’s consider the following factors:

1. Starting price: 460 euros.
2. Current condition: 85 (ebc-), which indicates good condition, although not the best.
3. Auction history: The coin has been auctioned 2 times in the past, and both times it sold. The average hammer price in the past was 480 euros.
4. Estimated price in the previous auction: In the December 2021 auction, the estimated price was 500 euros, but the hammer price was 460 euros, indicating that the market may have adjusted its value.

Given that the current condition is lower than that of the previous auction (90), and considering that the average hammer price is 480 euros, a reasonable maximum purchase price could be in the range of 480 to 500 euros, but since condition is an important factor, it is wise not to exceed the average hammer price.

Therefore, an estimated maximum purchase price could be 480 euros. This reflects the current market value and the condition of the coin.

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 80 (MS+), indicating that it is in fairly good shape, but not the best possible condition.

2. Historical Prices: Looking at previous auction prices for coins with similar conditions:
- In past auctions, coins with a condition of 80 have reached hammer prices that varied, but some examples are:
- 340 euros (2020-11-10)
- 330 euros (2020-07-02)
- 270 euros (2019-12-10)
- 240 euros (2018-05-30)
- The trend shows that hammer prices for condition 80 have been in a range of approximately 240 to 340 euros.

3. Starting Price and Average Hammer Price: The current starting price is 460 euros, which is significantly higher than previous hammer prices. The average hammer price for this coin is 284.7 euros.

4. Demand and Supply: The coin has been auctioned 175 times, with a high sales percentage (167 out of 175). This suggests that there is consistent interest in this coin, which could influence the price.

5. Recent Trends: In recent auctions, prices have shown an increase, especially for coins in good condition. However, the current starting price is quite high compared to historical prices.

### Maximum Purchase Price Estimate
Given that the condition is 80 and considering previous hammer prices, a reasonable maximum purchase price could be in the range of 300 to 350 euros. This is based on the fact that, although the starting price is 460 euros, previous hammer prices for similar conditions do not justify such a high price.

Therefore, an estimated maximum purchase price could be 350 euros.

To estimate a maximum purchase price for the coin that is going to be auctioned, we will consider several factors:

1. Condition of the coin: The coin in question has a condition rating of 95 (EBC+), which indicates that it is in very good condition. This generally translates to a higher price compared to coins with lower conditions.

2. Previous auction prices: By observing the hammer prices of coins with similar conditions (around 90-95), we can see that the hammer prices have varied, but in general, coins in good condition tend to reach higher prices. For example, in previous auctions, coins with a condition of 95 have reached hammer prices of up to 340 euros.

3. Starting price and average hammer price: The current starting price is 460 euros, which is significantly higher than the average hammer price of 272.63 euros. This suggests that the seller has high expectations for this auction.

4. Recent trends: In the most recent auctions, hammer prices for coins of similar condition have been in the range of 360 to 480 euros, indicating an increase in demand or value for these coins.

Based on these factors, an estimated maximum purchase price for this coin could be between 400 and 480 euros, considering that the condition is high and there is a recent trend towards higher prices in auctions. However, since the starting price is 460 euros, it is likely that buyers will be willing to pay a little more, especially if there is interest in the coin.

Therefore, a reasonable maximum purchase price could be 480 euros.
