1860 Liberty Seated Quarter. Type II/I. Proof-65 (PCGS). CAC.A richly and originally toned specimen with the most vivid colors reserved for viewing at direct lighting angles. This issue repeats a familiar theme from the Proof 1859 quarter. The Proof 1860 is also far scarcer than the mintage - in this case 1,000 pieces - might imply as the vast majority remained unsold and were subsequently placed into circulation by the Mint. Our offerings for Gems in recent decades have been particularly few, underscoring the significance of this opportunity for advanced collectors.PCGS# 5556.
