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 (VF-). This indicates that it is in an acceptable state, but not of high quality. In the past, coins with a similar condition have had auction prices that vary, but are generally lower than those in better condition.

2. Auction History:
- The average hammer price for similar coins has been 109.96 euros.
- In previous auctions, coins with a condition of 70 have had hammer prices ranging from 12 to 54 euros, depending on other factors such as demand and rarity.

3. Starting Price: The starting price is 12 euros, which suggests that the auction house expects moderate interest in the coin.

4. Recent Trends: In the most recent auctions, hammer prices for coins with similar conditions have shown a range that can reach up to 70-80 euros, but this depends on demand at the time of the auction.

5. Estimation Based on Historical Data: Given that the average hammer price is 109.96 euros, but considering the condition of 70 and the historical hammer price for coins in similar conditions, an estimated maximum purchase price could be between 50 and 80 euros.

Conclusion: Based on all these factors, an estimated maximum purchase price for this coin could be approximately 70 euros. This reflects a balance between the current condition and the historical hammer prices.

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

2. Auction History:
- The average hammer price for similar coins in the past is 116.27 euros.
- The condition of the coins that have been sold in the past varies, but there are examples of coins with similar conditions (75) that have sold for prices ranging from 25 to 80 euros, and some in better condition (85-95) that have reached much higher prices (up to 650 euros).

3. Starting Price and Average Starting Price:

- The average starting price for similar coins is 80.21 euros.

4. Recent Trends: In recent auctions, coins with similar conditions have had hammer prices that vary, but there is a pattern that coins in MBC condition (75) tend to sell in a range of 30 to 80 euros.

Based on these factors, an estimated maximum purchase price for the coin in question could be in the range of 80 to 120 euros. This is based on the auction price history and the current condition of the coin. However, since the starting price is 15 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 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 fairly good shape, but not the best possible condition.

2. Current Starting Price and Previous Prices: The current starting price is 90 euros, and the average starting price in previous auctions is 125.57 euros. This suggests that the current starting price is relatively low compared to the historical average.

3. Previous Hammer Prices: The average hammer price in previous auctions is 187.3 euros. This indicates that, in general, buyers are willing to pay significantly more than the starting price.

4. Recent Trends: In the most recent auctions, hammer prices have varied, but there are examples of hammer prices exceeding 200 euros for coins in similar conditions.

5. Demand and Supply: The coin has been auctioned 46 times in the past, with 39 sales, indicating good demand. Additionally, it will be auctioned in the coming days, which may increase competition and the price.

Taking all these factors into account, an estimated maximum purchase price could be between 200 and 250 euros. This is based on the average previous hammer price and the current condition of the coin. However, since the starting price is 90 euros, it may be possible to acquire it for a lower price if competition is not high.

Therefore, a reasonable maximum purchase price could be 220 euros.
