... and I am wondering if I should put some marks on it to make it more valuable. Mine is probably MS63. https://www.ngccoin.com/price-guide...-2-euro-km-276-2009-cuid-1187248-duid-1316656
I've found on NUMEROUS coins lately that NGC will say "$20" for the F Value, and then all the other numbers will be lower... like $1... lol. I think it is an error in their programming.
