This is a charming Gem dusted with iridescent autumn orange, lemon yellow, emerald green and salmon pink. The brightest and most vivid colors are best appreciated when the coin is viewed with the aid of direct lighting. Fully struck with a smooth satin to semi-reflective appearance, it is difficult for us to imagine a more appealing Proof Liberty nickel at the assigned grade level. A scarcer entry in this series, the 1910 was produced to the extent of just 2,405 Proofs. By way of comparison the 1909, which is the most plentiful Proof Liberty nickel in numismatic circles, has an original mintage of 4,763 pieces.,PCGS# 3908. NGC ID: 278L.,,From the Kiev Collection.
