A good resource on TR King large & small crown chips is the 3-volume set of auction catalogs of the Hank Boss collection, as auctioned through Doug Saito / Chip Chat. Each volume is in a 3-ring binder with pictures. All Nevada chips, I think. Maybe some TR King mfg. samples too.

In case you're not familiar with these catalogs, the club library has a set of them (see page 4 in the Library listing on the club website.)

The 3 catalogs are:
Chip Chat's Catalog of Hank Boss Collection #1 (LV only)

Chip Chat's Catalog of Hank Boss Collection #2 (Reno only)

Chip Chat's Cat of Hank Boss Collection #3 (Tahoe/small town)
