The casino name for the Pechanga $1 shows up a bit better with light grime on the rest of the outer ring. Similarly, the reverse hats-and-canes remain easily visible on the New York $1. This is even more useful where there are two mold varieties (Hats-and-canes vs. Long cane variant) especially with white Las Vegas $1 chips which get dirty fairly quickly. Neither chip shown is rare, so they could be cleaned if a new owner prefers that. But don't throw them into the washing machine with a scouring pad and lacquer thinner, just trust me on that.

Welcome to the hobby!
