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

2. Auction History:
- The average hammer price for this coin is 545.03 euros.
- In previous auctions, hammer prices have varied, but there are recent examples where the coin has reached hammer prices of up to 3200 euros (in the case of a condition rating of 85).
- The last auction with a similar condition (80) had a hammer price of 550 euros.

3. Starting Price and Average Starting Price:
- The current starting price is 300 euros, which is slightly higher than the average starting price of 258.09 euros.

4. Sales Trends: The coin has been sold in 34 out of the 36 times it has been auctioned, indicating good demand.

5. Projections: Given that the coin has a condition rating of 80 and considering the price history, a hammer price around 550-600 euros seems reasonable, as it is consistent with the average hammer price and the behavior of previous auctions.

### Estimated Maximum Purchase Price
Taking all these factors into account, an estimated maximum purchase price for this coin could be between 600 and 700 euros. This would allow for competitive bidding in the auction without exceeding the historical hammer value for similar conditions.

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 70 (MS-). This is an important factor, as coins in better condition tend to reach higher prices.

2. Previous Auction Prices:
- The average hammer price for coins with similar conditions (around 70) has been approximately 270 to 300 euros in previous auctions.
- There are examples of coins with conditions of 70 that have sold for prices ranging from 200 to 480 euros, depending on demand and other factors.

3. Starting Price and Average Hammer Price:
- The current starting price is 250 euros, and the average hammer price in the past has been 435.18 euros. This suggests there is potential for an increase in the hammer price.

4. Recent Trends: In the most recent auctions, hammer prices have been quite high, even reaching 1300 euros in some cases, although this may be related to higher conditions.

5. Demand and Supply: The coin has been auctioned 34 times in the past, with a sell-through rate of 97% (33 out of 34). This indicates there is consistent interest in this coin.

Based on these factors, an estimated maximum purchase price could be between 400 and 500 euros, considering that the condition is a limiting factor and that the average hammer price in the past has been 435.18 euros. However, if there is strong competition in the auction, the price could exceed this estimate.

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 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 in the past is 494.09 euros.
- In previous auctions, hammer prices have varied, but there are examples of sales exceeding 700 euros, especially in similar or better conditions.

3. Starting Price and Average Starting Price:
- The current starting price is 300 euros, which is slightly higher than the average starting price of 250.31 euros. This may indicate an expectation of a higher hammer price.

4. Recent Trends: In the most recent auctions, there have been sales reaching significantly high prices, such as 2400 euros in a previous auction with a condition of 95.

5. Estimation Based on Condition and Previous Prices: Given that the coin's condition is 80 and considering that in the past it has reached hammer prices of up to 750 euros in similar conditions, we can estimate that the maximum purchase price could be in a high range.

Therefore, a reasonable maximum purchase price could be 550 euros.

To estimate a maximum purchase price for the coin in question, we can analyze the provided data, including auction history and previous hammer prices.

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. Price History:
- The average hammer price for coins with a similar condition (85) in the past has been approximately 2,762.46 euros.
- In previous auctions, hammer prices for coins with a condition of 85 have varied, but there have been hammer prices of up to 3,300 euros (in the case of a coin with a condition of 95).

3. Starting Price: The starting price of the current auction is 2,000 euros, which is a reasonable starting point.

4. Sales Trends: The coin has been sold in 26 out of the last 30 auctions, indicating good demand.

5. Maximum Price Estimate: Given that the average hammer price is 2,762.46 euros and considering that the condition is 85, a reasonable maximum purchase price could be in the range of 3,000 to 3,500 euros, depending on the competition in the auction and the interest of other bidders.

Conclusion: An estimated maximum purchase price for this coin could be approximately 3,200 euros. This is based on the price history, current condition, and sales trend.

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

1. Starting price: 100 euros.
2. Current condition: 90 (EBC), indicating good condition.
3. Auction history: The coin has been auctioned once before, with a hammer price of 120 euros and a starting price of 100 euros.
4. Average hammer price: 120 euros, which is the average price it has sold for in the past.
5. Auction expectations: It will be auctioned again in the coming days, which may influence demand.

Since the current condition is better than that of the previous auction (90 vs. 75), and considering that the average hammer price is 120 euros, we could estimate that the maximum purchase price could be in a range above the previous hammer price.

Taking all these factors into account, an estimated maximum purchase price could be approximately 130-150 euros. This reflects the good condition and potential interest in the coin, as well as the price history.

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

2. Starting Price: The starting price is 2100 euros, which sets a baseline for offers.

3. Sales History:
- The average hammer price in previous auctions is 1328.4 euros.
- In recent auctions, hammer prices for coins with similar conditions (around 85) have varied, with some reaching up to 1700 euros or more.

4. Recent Trends: In the most recent auctions, hammer prices have shown an increase, with some reaching up to 1834 euros. This suggests an upward trend in the value of this coin.

5. Comparison with Previous Prices: Looking at previous hammer prices for coins with similar conditions, the range has been approximately 1300 to 1700 euros in recent years.

Based on these factors, an estimated maximum purchase price could be in the range of 1700 to 2000 euros, considering that the starting price is 2100 euros and that the condition is good. However, since the starting price is higher than previous hammer prices, it is possible that buyers may be willing to offer a bit more, but not necessarily reaching the starting price.

Therefore, a reasonable maximum purchase price could be 1800 euros.
