1882 Liberty Seated Dime. Proof-66 (PCGS).Warm lavender-gray patina blankets the obverse, while for the reverse we note smoky charcoal toning. Iridescent undertones are evident as the coin dips into a light, both sides also sporting sharp striking detail and pristine-looking surfaces. Handsome Gem quality from a Proof mintage of 1,100 coins.
