Jim - the same price guide I mentioned on your earlier post has it priced at $1-$2

in reality I think it's like $5 - $9 minimum

I qualify that by saying that the native casinos here in MN did a very good job of eliminating their old racks. There is no telling how few survived. [not too many].
and if they do have any old chips they are not parting with them.

Hope this helps
