Hello. Does anyone know the story on these $100 and $500 Tropicana chips? According to The Official U.S. Casino Chip Price Guide, they appear to be the 3rd issue chips and both are rated R-9. I've received (3) separate inquiries or offers in as many months from (3) different people regarding these same chips. Interestingly, these chips seem to travel as a pair as all (3) inquiries/offers contained both chips. Three inquiries/offers in such a short period of time is either a coincidence or there are more of these chips out there than initially estimated. Has anyone else had the same experience regarding these chips? Thanks.
