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

2. Previous Auction Prices: By observing the previous auction prices of coins with similar conditions (70-75), we can see that they have reached auction prices that vary, but are generally in the range of 60 to 160 euros. For example:
- In 2020, a coin with a condition of 70 was auctioned for 95 euros.
- In 2018, another coin with a condition of 70 was auctioned for 60 euros.

3. Average Auction Price: The average auction price for this coin is 158.53 euros, indicating that, in general, coins of this reference tend to reach higher prices.

4. Starting Price and Average Starting Price: The current starting price is 30 euros, and the average starting price is 70.72 euros. This suggests that the starting price is relatively low compared to the average auction price.

5. Recent Trends: In the most recent auctions, the auction prices have been quite high, which could indicate an upward trend in interest for this coin.

Taking all these factors into account, an estimated maximum purchase price for this coin could be in the range of 150 to 200 euros, considering that the condition is good and there is growing interest in coins of this reference. However, since the starting price is 30 euros, it could be a good opportunity to acquire it at a lower price if the competition in the auction is not high.

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

1. Condition of the coin: The coin in question has a condition rating of 80 (MBC+), which indicates that it is in relatively good shape. This is important because coins in better condition tend to fetch higher prices.

2. Previous auction prices: By looking at the hammer prices of coins with similar conditions, we can see that:
- In the past, coins with a condition rating of 80 have reached hammer prices of up to 280 euros (in 2011).
- The average hammer price for coins of similar condition seems to be around 85.8 euros.

3. Starting price and average starting price: The current starting price is 40 euros, and the average starting price in the past has been 68.32 euros. This suggests that the current starting price is relatively low compared to the historical average.

4. Sales trends: The coin has been auctioned 142 times, of which it has sold 78 times. This indicates that there is considerable interest in this coin, which may influence the hammer price.

Based on these factors, an estimated maximum purchase price could be in the range of 120 to 200 euros, considering that the condition is good and there are precedents for higher hammer prices in the past. However, given the starting price of 40 euros, it is likely that the hammer price will not significantly exceed 200 euros unless there is intense competition among bidders.

Therefore, a reasonable estimated maximum purchase price could be 150 euros.

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

1. Condition of the coin: The coin has a condition rating of 70 (VF-), indicating that it is in acceptable condition but not of high quality. This generally affects the price, as coins in better condition tend to fetch higher prices.

2. Current listing price and previous prices: The current listing price is 60 euros. The average hammer price in previous auctions for similar coins is 231.34 euros, suggesting that there is significant potential for the hammer price to be much higher than the listing price.

3. Auction history: The coin has been auctioned 522 times, with 468 sales. This indicates that there is an active market for this coin. Additionally, previous hammer prices for coins with similar conditions (70) have varied, but some have reached hammer prices of up to 240 euros.

4. Recent trends: Looking at the most recent auctions, hammer prices for coins of similar condition have shown a range that can go from 60 euros to over 200 euros, depending on demand and collector interest.

Based on these factors, an estimated maximum purchase price for this coin could be in the range of 200 to 250 euros. This range takes into account the condition, price history, and recent market activity. However, it is important to note that the final price may vary depending on competition in the auction and collector interest at that time.

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

2. Auction History:
- The average hammer price for coins with a similar condition (90) in the past has been 71.21 euros.
- In previous auctions, hammer prices for coins with a condition of 90 have reached up to 113.47 euros (in 2012).
- There are also examples of coins with a condition of 90 that have sold for lower prices, such as 48.31 euros (in 2015).

3. Starting Price and Trends:
- The current starting price is 50 euros, which is slightly lower than the average starting price of 52.34 euros.
- Since it has been auctioned 33 times in the past and has sold 21 times, there is good demand for this coin.

4. Future Projections:
- The estimated price for the next auction is 150 euros, suggesting that there are expectations for the coin's value to increase.

Based on these factors, an estimated maximum purchase price could be in the range of 100 to 120 euros. This is based on the auction price history for coins of similar condition and the trend of increasing value for the coin.

Therefore, a reasonable maximum purchase price could be 110 euros.

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