1891 Liberty Seated Quarter. Proof-66 (PCGS). CAC. A pretty piece with undeniable originality to the surfaces, the obverse exhibits iridescent copper-apricot toning that appears to drift toward the rim. For the more boldly toned reverse we note dominant antique copper patina with subtle cobalt blue highlights to the central devices. Bright, reflective and uncommonly well preserved for this final year issue in the proof Liberty Seated quarter series. Among the finer survivors from this mintage of 600 pieces. Just eight coins have been certified finer by PCGS in this category. From the Harrington Collection. Earlier ex our November 2011 Baltimore Auction, lot 2094.
