Some I found in my dupes box.

The Diamond-flush is a Chipco sample.

Notice the Nugget Carson City is the older "no underline" version.

The Horseshoe "Harrington" is an add-on chip, not in the first set of 20.

The Gaming Times chip was made to commemorate one of Bill Akeman's LV chip shows. He also published a collectibles magazine by that name.

The plain pink Four Queens is the first one to say "snapper" on it that I know of; maybe the only one? Only Gene knows.

Top three rows are $5 each
Next three rows are $10 each

$2 shipping for any number of chips.
