I recently acquired 2 chips in an eBay auction that the seller attributed to a Sheraton casino in Cuba. The 2 chips are both red with a small greek key mold and are in worn/damaged condition. I was able to determine that, at least one if not both, are listed in Black's Puerto Rico Chip Catalog as SHR-1 from the Puerto Rico Sheraton, with the following differences:

o One chip has the original hot stamp completely worn off and a new hot stamp has been added that says "$1.00 Free Play"

o The other chip has much of the original hot stamp, I am certain it is a SHR-1, although part of the hot stamp has been scrapped off, and a 2nd hot stamp of "No Cash Value" has been added around the center of the chip, identicle to that of the $5 chip, SHR-5e

Are these previously unknown chips? Is it likely that they are all from Puerto Rico, Cuba or both?
