I think what made the 1999 so popular is the first year either most people didn't know about them or just weren't interested in them at all until they saw their home state on a quarter and that is when they started trying to put a whole set together and they needed that first year of series to complete the set and since they weren't all that popular there weren't allot of sets to go around. You had a choice collect what you could get out of pocket change and put them in the 50 state folder thingy, collect the clad versions that were the same composition as the pocket change for a premium or collect the silver sets which was a little different than the pocket change pieces because their composition was different and it was more than just a different mint mark from the ones you saw everyday
