I've found 50 or so of these now with dates varying. I mean it seems like they're fairly common. Do you all consider these 2x2 worthy? I don't mean one that is in bad shape but let's say xf or au condition. Thanks.
2x2 the stronger or more unusual ones. The small ones, if you want to keep them, put in envelopes or ziplocs. After searching for a few years you could get hundreds of these. Don't use up all your cardboard and staples!
