2. Auction History:
- The average hammer price for similar coins has been 133.95 euros.
- In previous auctions, coins with a similar condition (around 70) have had hammer prices that varied, but some examples are:
- 120 euros (2020-12-15)
- 140 euros (2020-11-19)
- 130 euros (2019-05-23)
- The trend shows that coins with a condition of 70 have reached hammer prices in the range of 100 to 140 euros.

3. Starting Price and Estimated Price:

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

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

2. Auction History:
- In the past, coins of the same reference with condition ratings of 90 and 85 have been auctioned, reaching hammer prices of up to 380 euros.
- The last auction with a condition rating of 85 had a hammer price of 380 euros, indicating that there is a market willing to pay high prices for well-preserved coins.

Therefore, a reasonable maximum purchase price could be 350 euros.
