The classic 10th issue ‘Joshua Tree’ $5 HCE mold from the Desert Inn, Las Vegas. Typical average wear but as such a really fresh looking example. Listed with a rarity of R-6 in The Official U.S. Casino Chip Price Guide but probably under-rated in this condition as most examples show greater wear. Still missing from many collections.
worth $300-$350 in average condition
