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 70 (VF-). This indicates that it is in an acceptable state, but not of high quality. In the coin market, condition is a crucial factor that affects price.

2. Auction History:
- The average hammer price for similar coins in the past has been 4299.47 euros.
- The coin has been auctioned 43 times, of which 39 have been successful sales. This indicates good demand in the market.
- Previous hammer prices for coins with similar conditions (70) have varied, but there are examples of auctions that have reached up to 3600 euros in recent sales.

3. Starting Price: The current starting price is 750 euros, which is relatively low compared to the average hammer price.

4. Price Trends: Observing the hammer prices of coins with similar conditions, the range seems to be between 1200 and 3600 euros, depending on demand and other market factors.

Based on these points, an estimated maximum purchase price for this coin could be in the range of 3000 to 3600 euros. This range takes into account the current condition, price history, and market trends. However, it is important to note that the final price may vary depending on competition in the auction and other external factors.

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 80 (MBC+), which indicates that it is in fairly good shape, but not the best possible condition (FDC).

2. Previous auction prices: By looking at the hammer prices of coins with similar conditions (around 80-85), we can see that the hammer prices have varied, but generally have remained in a range of 480 to 750 euros.

3. Starting price and average hammer price: The current starting price is 650 euros, and the average hammer price in previous auctions is approximately 630.98 euros. This suggests that the starting price is aligned with the market value.

4. Auction trends: The coin has been auctioned 89 times, with a high sales percentage (86 out of 89). This indicates that there is consistent interest in this coin, which may influence its price.

5. Recent hammer prices: In the most recent auctions, hammer prices have been in the range of 600 to 800 euros for coins of similar condition.

Based on these factors, an estimated maximum purchase price for this coin could be around 750-800 euros. This is because, although the starting price is 650 euros, the interest in the coin and its condition suggest that it could reach a higher price at auction.

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

2. Current and previous prices: The current starting price is 675 euros. In previous auctions, we have seen hammer prices that vary, but there are examples of hammer prices exceeding 700 euros, especially for coins in similar or better conditions.

3. Price trends: Looking at previous hammer prices for coins with a condition of 80, the highest hammer price was 700 euros, while other hammer prices in similar conditions have ranged from 600 to 800 euros.

4. Average hammer price: The average hammer price for this coin is 627 euros, suggesting that the market is willing to pay around this amount on average.

5. Auction expectations: Since there are no auctions scheduled in the coming days, this could increase interest in the current coin, potentially leading to a higher hammer price.

Taking all these factors into account, an estimated maximum purchase price for this coin could be around 800 euros. This price reflects both the good condition of the coin and the price trends observed in previous auctions.

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

2. Auction History:
- The average hammer price of similar coins in the past is 3936.17 euros.
- The average starting price is 2649.42 euros.
- Previous auctions of this coin have shown hammer prices that vary significantly, from low prices (such as 439.99 euros) to higher prices (such as 12834.03 euros).

3. Price Trends:
- Coins with higher conditions (such as 80 or 90) have reached significantly higher hammer prices. For example, a coin with a condition of 90 has sold for over 6000 euros on several occasions.
- A condition of 70 is lower than many of the coins that have sold for high prices, suggesting that the price of this coin will not reach those levels.

4. Starting Price: The starting price is 800 euros, indicating that the seller has expectations of a minimum price.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 1500 to 2500 euros, considering that the condition is not the best and that the price history shows significant variations. A hammer price around 2000 euros could be a reasonable target, given the auction history and current condition.

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

1. Coin Condition: The coin to be auctioned has a condition rating of 90 (EBC), indicating that it is in quite good shape. This is important because coins in better condition tend to fetch higher prices.

2. Starting Price and Previous Prices: The current starting price is 900 euros. In previous auctions, we have seen hammer prices that varied, but there are examples of hammer prices exceeding 1000 euros, especially for similar conditions.

3. Average Hammer Price: The average hammer price for this coin is 1250.38 euros, suggesting that, in general, buyers are willing to pay more than the starting price.

4. Recent Trends: In the most recent auctions, hammer prices have ranged from 700 to 950 euros for coins with conditions of 90 and 80. However, there is also an extreme case where a similar coin sold for 16500 euros, which could be an outlier.

5. Analysis of Previous Prices: Looking at the hammer prices from previous auctions with similar conditions, the highest recorded price was 16500 euros, but this seems to be an exceptional case. Most hammer prices for conditions between 80 and 90 are in the range of 700 to 950 euros.

Based on these factors, an estimated maximum purchase price for the coin in question could be in the range of 1200 to 1400 euros, considering that the average hammer price is 1250.38 euros and that the coin's condition is good. However, since the starting price is 900 euros, it is likely that buyers will be willing to bid more, especially if there is interest in the coin.

Therefore, a reasonable maximum purchase price could be 1300 euros.
