I am thinking:

a) they probably are not being treated as tourney "chips" as their purpose is to facilitate an "all-in" move, and have no other tourney value.

b) they must have mada at least 3,000 of them.

c) as a player busts and walks away in disgust/pain/ etc., they would leave the button and I guess the dealers (many "temp" dealers) collect them. It would take alot of work to keep track of them and I would imagine this is not too high on the pecking order. I could see where quite a few would come thru.

Just conjecture, trying to get a bit of a handle on what they would wind up going for.....anyone with an accurate insight care to comment?
