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

1. Starting Price: 70 euros.
2. Condition: The coin has a condition rating of 75 (MBC), indicating that it is in fairly good shape.
3. Auction History:
- It has been auctioned 5 times in the past, of which it has sold 4 times.
- The average hammer price in previous auctions is 108.75 euros.
- In the most recent auction (2023-12-18), the coin was hammered at 40 euros, but in a previous auction (2020-04-29), it was hammered at 250 euros, indicating variability in prices depending on demand and condition.

4. Average Starting and Hammer Price: The average starting price is 50 euros, but the average hammer price is significantly higher (108.75 euros), suggesting that buyers are willing to pay more than the starting price.

Given that the condition of the coin is good (75) and considering the hammer price history, an estimated maximum purchase price could be positioned in a range between the average hammer price and a bit more, given that the coin has a starting price of 70 euros.

Estimated Maximum Purchase Price: It could be reasonable to estimate a maximum purchase price of around 150-200 euros, taking into account the hammer price history and the condition of the coin. This would allow for competitive bidding in the auction without exceeding the market value observed in previous auctions.

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), indicating that it is in an acceptable state, but not among the best qualities.

2. Auction History:
- The average hammer price for similar coins has been 245.43 euros.
- In previous auctions, we have seen hammer prices that varied significantly, ranging from 50 euros to 1200 euros, depending on the condition and other factors.

4. Price Trends: In recent auctions, coins with similar conditions have reached hammer prices ranging between 100 and 290 euros.

5. Analysis of Previous Prices:
- In auctions with conditions of 75, hammer prices have been around 60 to 360 euros.
- The most recent auction with a condition of 75 had a hammer price of 360 euros.

Based on this data, an estimated maximum purchase price for this coin could be in the range of 200 to 300 euros, considering that the condition is an important factor and that the average hammer price is significantly higher than the starting price.

Therefore, a reasonable maximum purchase price could be 250 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 (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 coins with a similar condition (75) in the past has been approximately 60-70 euros.
- In previous auctions, coins with a condition of 75 have reached hammer prices of up to 110 euros, as seen in the auction on 2023-02-16.

3. Starting Price and Average Starting Price: The current starting price is 35 euros, which is below the average starting price of 53.39 euros. This suggests that there is potential for the hammer price to be higher.

4. Recent Trends: In the most recent auctions, the hammer price has shown a trend of being higher, especially for coins in good condition.

Based on these factors, an estimated maximum purchase price for this coin could be between 80 and 110 euros, considering that the condition is favorable and there is a history of hammer prices that supports this estimate.

Therefore, a reasonable maximum purchase price could be 100 euros.

4. Current Starting Price: The starting price is 350, which is relatively low compared to previous hammer prices.

5. Sales Trends: The coin has been auctioned 15 times, of which 14 have sold, indicating good demand.

Based on these factors, especially considering the condition and previous hammer prices, an estimated maximum purchase price could be in the range of 1500 to 2000 euros. This is based on the fact that, although the condition is slightly lower than some of the coins that have sold for higher prices, the price history and demand suggest it could reach a significant price.

Therefore, an estimated maximum purchase price could be approximately 1800 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 75 (MBC), indicating that it is in an acceptable state, but not among the best qualities.

4. Current Starting Price: The starting price is 100 euros, which is relatively low compared to the average hammer price.

Based on this data, an estimated maximum purchase price could be set in a range that considers the average hammer price and the current condition. Given that the condition is 75, a hammer price in the range of 300 to 500 euros seems reasonable, considering that there have been previous auctions in that range for similar conditions.

Therefore, an estimated maximum purchase price could be around 500 euros. This allows for a margin for competition in the auction and aligns with historical hammer prices for coins in similar conditions.

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 85 (ebc-), indicating that it is in quite good shape. This generally translates to a higher value compared to coins with lower conditions.

2. Auction History:
- The average starting price for similar coins is 72.81 euros, and the average final price is 77.58 euros.
- In the past, this coin has had starting prices ranging from 50 to 176.78 euros, with final prices reaching up to 200 euros on some occasions.

3. Sales Trends: Out of the 17 times it has been auctioned, 12 have sold, indicating a reasonable sell-through rate. This suggests there is interest in the coin.

4. Current Starting Price: The starting price is 60 euros, which is relatively low compared to the average starting and final prices of similar coins.

5. Previous Estimates: In previous auctions, estimated prices have varied, but generally, final prices have been in the range of 60 to 100 euros for similar conditions.

Taking all these factors into account, an estimated maximum purchase price could be around 90-100 euros. This is based on the condition, interest in the coin, and previous final prices. However, it is important to remember that the final price may vary depending on competition in the auction and other market factors at the time of sale.

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

1. Current condition: The coin has a condition of 80 (MBC+), which is lower than the condition of 90 from the previous auction. This suggests that the value could be less than the estimated price of 238.33 euros from the previous auction.

2. Starting price: The starting price is 40 euros, indicating that the seller has a low expectation compared to the previous estimated price.

3. Auction history: The coin has been auctioned once in the past but did not sell. This may indicate that interest in the coin is not high, which could affect its price.

4. Current demand: The coin will be auctioned again in the coming days, which could generate a bit more interest, but the fact that it did not sell previously may limit the price.

Given that the current condition is lower than that of the previous auction and considering the starting price, an estimated maximum purchase price could be between 60 and 80 euros. This reflects an increase over the starting price but also takes into account the lower condition and the auction history.

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

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

4. Sales Trends: Out of the 20 times it has been auctioned, it has sold 14 times, indicating a good sales rate. This suggests that there is demand for this coin.

5. Comparison with Previous Prices: Looking at previous hammer prices, the range has been quite broad, but the highest prices have been for coins in better conditions than the current one.

Taking all these factors into account, an estimated maximum purchase price could be around 180-200 euros. This is based on the average hammer price and the price trends for coins of similar condition. However, it is important to consider that the final price may vary depending on competition in the auction and the interest of other buyers.

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 relatively good shape. This suggests that its value should be above that of coins in worse conditions.

2. Auction History:
- The average hammer price in previous auctions is 75.33 euros, suggesting that, in general, coins of this reference tend to sell for significantly higher prices than their starting price.
- In past auctions, we have seen hammer prices vary, but there are examples of sales reaching up to 300 euros (although this may be an exceptional case).

3. Starting Price and Previous Prices:
- The current starting price is 20 euros, which is relatively low compared to the average hammer price.
- In previous auctions, the highest hammer price for a coin with a similar condition was 120 euros.

4. Auction Trends: Since there are no auctions scheduled in the coming days, this could increase competition among bidders, potentially leading to a higher hammer price.

Taking all these factors into account, an estimated maximum purchase price for this coin could be in the range of 100 to 120 euros. This is based on the hammer price history and the good condition of the coin. However, it is important to remember that the final price may vary depending on demand at the time of the auction.

- In recent auctions, hammer prices have varied, but there are examples where hammer prices have reached up to 270 euros (although with a higher grade).
- The last auction with a grade of 80 had a hammer price of 190 euros.

Given that the grade of the coin in question is 70 (MBC-), which is lower than the grades of some coins that have sold for higher prices, but still an acceptable grade, we can make an estimation.

### Estimation of the maximum purchase price:
- Considering the average hammer price (119.17 euros) and the fact that grade is an important factor, a reasonable maximum purchase price could be in the range of 120 to 150 euros. This is based on the fact that the coin has a history of successful sales and a hammer price that exceeds the starting price.

Therefore, an estimated maximum purchase price could be 150 euros.
