1. T R King did make Small Crown chips for Tropicana in Las Vegas.

2. There are several Tropicana Casino world wide but their dates of operation and locations don't fit the Small Crown area of distribution or era of use.

3. Jamison found a Trop chip that has the same color and markings as my "Sample Tropicana".

With the above in mind - I stand by the probability that this Sample was made for the Tropicana in Vegas. Can't be 100% sure but it looks very possible to me. I am sure there are a lot of chips in TCR with a lot less plausible attribution !!!
Take care,
