1908 Liberty Nickel. Proof-67+ (PCGS). CAC.;A breathtakingly beautiful condition rarity that belongs in the finest numismatic cabinet. Dressed in warm apricot-gray patina, both sides are fully struck with a lively satin to semi-reflective finish from the dies. A limited mintage for the type of 1,620 pieces helps to explain why the 1908 is among the more elusive Proof Liberty nickels. In Superb Gem preservation, as here, this issue is nothing short of rare.
