What I have are chips which are part of a limited numbering. No #1 of's or 2 of's. Just some chips which I thought looked cool. With the sets I do have they do atleast all match in the series. I am not into these things like some are, this hobby has many folds to it, as most do, some get into so deep that, for me, it would not be fun anymore, some just grab things they like, sort of like how y'all started out.
Some go further, some don't.
Later,
Mark
