I'm afraid some valuable history has been lost in the cataloging of the Golden Nugget GN mold roulettes, though. TCR 11th edition lists every table as being known with all the colors and all having the same value. They also have been devalued from an "I" to a "D" value code.

There was a lot of collector input to this series over the years to indicate which color/table combinations were known to have survived. This has been lost, as well as the record of which combinations are hard to find. I'd suggest that any of the older Nevada roulettes (1950's and 1960's) retain individual value codes in the next TCR. This doesn't necessarily mean separate TCR numbers for each combination; just a way to indicate value differences.

The Harolds Club H-mold chips are another example where the documentation of which color/table combinations are known to collectors has been lost. Maybe someone has collectrd all the "table 13" colors, but I haven't been able to find them.

Perhaps this specialized area deserves a separate chip guide? Not everyone who collects Nevada cares, but a few of us do.
