Foxwoods, I remember looking these up a few years ago when I wanted to put stickies on the boxes and found what each was based on the codes on the outside of the boxes. But now I can't get into the account since it's been so long since I logged on.
I can call the mint tomorrow and have them reset my email address so I can get a new password. I can then see my orders there and figure out which box is which sets (at least that is what I hope!). I need to know that for when I send them in for grading since there are different numbers of coins in each box, as well as several sets per box in some cases.
Otherwise, I would just set up a new account.
