"I like this discussion!! ----- jim o\-S"

I guess there are a few who don't care for it Jim.... and that's o.k. too. <g>

Regarding your "dung" comparison.... While there may not be much demand for ancient dung by chip collectors... I'm sure there are more than enough scientific "dung collectors" would go ape-s..t over it.... which spells "demand".<g>

I think I'll devise my own rarity scale Jim. If anyone else would care to adopt it, I give them my express permission to do so. I'll call this the "Official Rarity Scale by Black" (or "Black's Scale"). We don't need all the numbers in the beginning and the end that seem to give some chippers big problems... the millennium debate comes to mind.

Chips up to the $5 denomination selling for single digits would be considered "common".
Chips up to the $5 denomination selling for double digits would be considered "uncommon", double face and up for $25 denomination chips would also be "uncommon".
Chips up to the $100 denomination selling for triple digits would be considered "scarce"
Chips up to the $100 denomination selling for four figures and up would be considered "rare".

That's it... four simple definitions for my rarity scale. I think that I may consider publishing this scale in my year 2000 issue of "Atlantic City Casino Chips and Gaming Tokens Catalog". Then I can be a respected rarity expert too. After all, if it appears in print, it must be so! <g>
Oh, one final note. Notice the term "selling for"... which differs significantly from "asking for".
