The 60-chip sets of Paul-son H&C chips in all the colors have been popular each time I've been able to assemble one. There is one in an eBay auction now with a $35 bid. This one includes the black, white, and yellow colors that are used for high-denom casino chips and that are no longer offered in personal poker chips.

These are hot-stamped with the Paul-son weird color names and are a help in discriminating between some of the chips that are almost, but not quite, the same color. They also make an impressive framed display.

See the pic below and the link to the auction.
