Truly a SPECTACULAR Proof Liberty nickel. The sole FINEST graded at PCGS and with its stunning rings of rainbow toning around the rims on both sides, this SUPERB GEM is bound for the FINEST of sets. We marvel at the ultra-high end visual allure. Rich, reflective mirrors have a smooth and flashy texture. The peripheral toning is gorgeous with bold rainbow patina around bold, nickel-silver surfaces at the centers. The devices are sharply struck and frosty. The eye appeal is simply AMAZING. PCGS 1, NGC 1. Unpriced in the PCGS Price Guide in PR68 but listed at $6,500 in PR67+. As the SOLE FINEST graded at PCGS, anyone building the highest ranking PCGS Registry Set of Proof Liberty nickels needs this stunner. We can see it bringing a record price for the date and designation when the hammer falls. Good luck! Cert. Number 37904796 PCGS # 3893
