Here are several white embossed chips with colored suits that I came across. These are cataloged by Seymour as PC-GP and are valued as a "G" (pretty scarce at $10-14).

If you'd like one for your collection and a few to to trade or sell, here are seven of the white chips that can be yours for $25 delivered in USA.

Note that although some embossed poker chips are pressed paper, these are a hard composition, probably clay or clay-composite.
