AI Recommendation
Given that the coin has a conservation rating of 100 (S/C), indicating that it is in almost perfect condition, and considering that this is the first time it is being auctioned, the starting price is set at 900 euros.
In this case, since there are no historical sales data for this coin, the estimated maximum purchase price could be slightly higher than the starting price, especially if there is interest in the coin.
An estimated maximum purchase price could range between 1,200 and 1,500 euros, depending on the demand at the auction. This is based on the high conservation rating and the novelty of the auction. However, the final price will depend on the competition among bidders.
