but in my opinion, casino chips and the buying and selling of casino chips has never been more popular.

I think that Amazon is hard to compete with when selling general merchandise, like Spinettis does. but... I'd bet, that in general...
there has been a steady increase in the volume of online sales of casino related memorabilia on ebay over the last
20 years.

I do not think the CCA's membership trends represent the general casino chip collecting trends. There seems to be a disconnect between
the two as far as I've noticed.
