The ivory chips depicted in the catalog of dominoes, chessmen, draughtsmen; dice, colour counters and dice cups... are non-denominated. Only the prices are listed.

For example:

The smallest ivory chips are listed @ 5/- per dozen (several sizes listed; per dozen: 6/, 7/6, 11/- and 18/6)...

...and the largest ivory chips listed (approx. 1-1/2") sold for 26/- per dozen.

They list solid, thick and heavy ivory Draughtsmen like mine below (only mine are super-thick and much wider - 5/8" thick and 1-3/4" wide) for 170/- per set of 30-pieces.... I'm selling my pieces for $100 EACH; Brown/Natural and Natural... and my pups have a groove around the girth not seen on lesser-quality pieces. Some of the pieces w/ edge chips and nerve-hole fractures sell for 50% less.
