I am told that this chip is from the Parque Hotel in Montevideo , Uruguay. The reverse side has a red horseshoe. Walt D sold a similar one on eBay awhile back, and told me it was not a roulette, but I cannot recall how the denoms were assigned. Maybe he will see this thread and straighten me out
In any case, I'll sell this chip for $7 including the new (always varying) shipping fees.
I would also happily trade it for any jeton I am missing. I have a scan of the reverse side for anyone who is interested.
