Here are three different $5 harrah's chips with the metal rings attached, one is sm-key, one is Scrown, and the other H&C. In James's book there is mention of the Scrown and Sm-key, but no mention of rarity or value, and no mention at all of the H&C veriation. The TCR lists the Scrown as N6600 with a O value, but no mention of the Sm-key or H&C veriations. looks like the Sm-key and H&C should be added to the TCR. Doe's anyone know of a value or rarity of these. This is the first H&C I have seen.
