Extraordinary condition rarity for this early Proof entry in the popular and widely collected Washington quarter series. The obverse exhibits hazy russet toning around the peripheries, a bulls eye of pale ultramarine and violet at the center, while the reverse is near blast-white with a halo of light russet-gold at the rims. Subtle rainbow hues are also evident on the latter side when examined under a glass. Truly unsurpassed quality for the collector seeking perfection.This delightful condition rarity ranks as equal to the best extant at Proof-68. PCGS has graded only four at this level, and none higher, with NGC also failing to evaluate a higher grade as well. The coveted CAC sticker has to push this coin to the top of the stack, giving it fair claim to being the finest known.,,PCGS# 5978. NGC ID: 27HS.,PCGS Population: just 4; 0 finer.,
