It is unusual for a casino to have a $1 and a $5 chip in the same color, and the inserts are almost the same too, except for Puerto Rico. If you click on the Dupont Plaza page on the Caribbean ChipGuide, you will see 16 different color combinations for the $1 chip, 8 variations of the $5 chip and 3 variations of the $25 chip. Why so many variations? They used denomination chips on the roulette tables. So, technically these are roulette chips, but unlike roulette chips in other locations, some Puerto Rico casino used chips with denominations on the roulette table. Checking out the Puerto Rico casinos on the Caribbean ChipGuide, you can find many casinos with multiple color combinations for $1, $5 and even $25 chips with the same molds and inlays for use on the roulette tables.
