1890 Liberty Seated Quarter. Proof-66+ Deep Cameo (PCGS). CAC. A breathtakingly beautiful premium Gem that ranks among the finest certified Proof Motto Liberty Seated quarters irrespective of date. Boldly impressed with a rich satin texture, the devices appear to float atop deep pools of reflectivity in the fields. The entire package is free of both toning and grade-limiting blemishes to allow ready appreciation of a stark cameo finish. The Philadelphia Mint delivered only 590 Proof quarters in 1890, the lowest mintage for the Liberty Seated series since 1877. This is an extraordinary strike and condition rarity for the date, which enjoys strong collector demand as the penultimate for this long-lived type. PCGS# 95591. NGC ID: 23XN.
