I don't have a spreadsheet with amounts paid, nor who, or where I got it from. Some I can and will always remember, but others I don't and have pondered wheather I should have something that I didn't prize enough to remember where it came from. I very recently dove into my pile of "prized stuff" to retrieve a not forgotten item, but one I had abandoned the quest for a set four years ago. I can quite remember what I gave for it but can't remember from whom I got it. This one time in all my years, this I wish that I could remember. Am I the only one? Do you keep meticulous records of your entire collection? Do you have "prizes" you will remember the details forever with no written history? I post this in the paper money forum because what brought about this thread was paper money related, but all collectors can and should chime in.
