My wife was just in eastern Europe for a few days and get these for me. I have a few traders. The Tropicana chip is a $1 chip, shows on the reverse. The Casino Royale chip has a nice wreath logo on the reverse. Does anyone have any info about the Czech Casinos chip? It seems to have a paste on inlay. Underneath it looks like the inlay says "Czechloslavokia Casinos". The "C" on the mold indicates that this casino is managed by Casinos Austria.
