Quote from MEHART website “The prohibitively rare CIOQ-1 is the only 1902-dated California Indian Octagonal Quarter die variety.” R8. Mike Locke owns the only other one known to exist. Only 2 certified with this one being the finest certified by several grades. NGC MS67! The other one certified MS63. We were fortunate to discover this great rarity and purchase it. It’s extremely doubtful that you will see one come up for sale anywhere again. A true extreme rarity for the finest of California fractional collections.
