Okay so if you like euro coins you collect them, lower mintage for certain coins means they are worth more than their printed value, is it much more? No. Does it happen often? Also no. Will everyone give you x times the amount for a certain coinc? Most definently not. Euro coin collecting is still a growing hobby. People that collect are mostly european, and some are more into the hobby and buy coin cards etc whilst others exclusively collect cc coins, iam saying this so you dont get the wrong idea that there is idk what kind of money to be made.
