1959-D Washington Quarter. MS-66 (PCGS). CAC. The obverse is the more boldly toned of the two sides of this frosty Gem, splashed with mottled antique copper and autumn-orange patina. The reverse is lightly toned in iridescent pink, gold and blue with subtle copper-russet highlights around the periphery. Like its identically dated Philadelphia Mint counterpart, the 1959-D is surprisingly scarce in the finest Mint State grades for a late date 90% Washington quarter with a mintage of 62,054,232 coins. A find for the astute Washington quarter enthusiast.
