Pricing on individual chips is commonly much higher than on a hundred chip rack of the same chip.
Don't believe a word in a glossy chip guide. Not-A-Word. The pictures are pretty though.
The market for individual chips can be exploitive. Sadly, there are lots of suckers that can be fleeced.
"market" pricing is hard in general. Lots of sales are private or "best offer" sales where we don't know the true price. Lots of single chips sit unsold for months on
eBay before the aforementioned sucker buys it.
The best market price comes from a sale where there is a true auction with several bidders. But such chips are commonly the very most desirable and expensive.
Bottom line, most vintage casino chips are worth less than $5 - often more like $1. Vintage chips not from a casino are rarely worth a dollar, mostly worth a quarter.
But if something calls your name, so what if you get fleeced for $10? -=- DrStrange
