I have some extra roulettes from Sahara Tahoe in their earlier years (1960's). All are smooth mold and are of the crest and seal style. All seven are different, including the two brown table 1 chips; note the style of the numeral on the two chips. There apparently was a reorder of all the chips, as you can find two varieties of each color for each table.

Price is $15 a chip, plus postage. If you need all seven, price is $100 and I pay postage.
