Based on the data provided, we can observe that the coin has had an average auction price of 110.17 euros in the past. Additionally, the condition of this coin has been described as 75 (VF).

Considering that the condition of the coin is 75 (VF) and the historical average auction price is 110.17 euros, we can estimate a maximum purchase price for this coin in a future auction. Since the condition is not the best, it is advisable to adjust the estimated price accordingly.

Therefore, my recommendation would be to set a maximum purchase price around 100 euros for this coin in the next auction. This would take into account the condition of the coin and ensure a possible acquisition at a reasonable price.
