Thank you Catbert, I will keep all of that in mind when it comes to my collecting. Although it seems that it would be easy to keep a few of those dimes, it would be really hard. She is not doing too well at all (lyme disease). And my father wouldn't understand how valuable these dimes really are to me (he's not a coin collector).
Maybe I'll take a look at those 20th century type folders. I've never done it but it must be a great feeling when you complete a set.
