The Crumley chips came out several years ago already in a large number but the chips did not seem to be in this good of condition.
The Freemont $5 chips I've seen in the past have been in regular worn condition, not unused like the ones for sale on E-Bay.
These chips appear to be the real deal but I've always been cautious of chips that appear new. If you think about it, why would anyone save the junk when there are several boxes of like new chips to set aside.
In regards to where these chips come from; from farsighted individuals that had access to said chips and saved them until they thought it was the right time to sell them.
Will there be more, Oh Yes!!!!!!! Will there be as many in the future available, I don't think so................
