Just like Ivory Snow being 99 & 44/100% pure the same percentage of tokens have been issued.
A small percentage of the issued tokens were designed to separate a persons money as is the current status of 'limited edition' casino chips.
Just about anyone can have a reasonable collection of slot tokens, not silver strikes, for a relatively modest investment. I am speaking of those issued for gaming purposes, not gimmicks.
Only Colorado has issued gold, gold plated, sterling and platinum tokens in any quantity. They, in my opinion, are not slot tokens.
My personal collection of actual slot tokens is about 90+% complete and I enjoy collecting and locating missing items, trading with other collectors and sharing knowledge.
Next to my son's memorial project tokens are the next best thing to buttered bread.
Jim mentioned TITO's. Tokens don't fade .
Wishing all enough,
