I recently bought a small collection that included some $5 and $1 chips from the Park Tahoe, which was open for about a year in the late 1970s (where Caesars Tahoe is now). The $5 chip is N4477 in TCR ($40-$49), and the $1 chip is N0972 ($15-$19). They show very slight evidence of table play but are in great condition overall. I'm selling the pair for $20, including shipping. I have a few sets available. I'll also consider trade offers for similarly valued chips from northern Nevada. Please e-mail me if you're interested. Thanks.
