PCGS Proof-65 Brown (illustrated above).  Ex - Early American History Auctions, Inc.'s Mail Bid Sale, October 14, 2000, Lot 1162, where it was described as follows: "Original.  A shimmering Proof with 10% of the original mint red still remaining (the rest has toned down to a glittering reddish-brown color). This was one of the Mint’s first attempts at reducing the size and weight of the clunky Large Cents. The size of the coin is 25 millimeters, compared with the 27.5 of a normal Large Cent and the 19 millimeters of the Small Cents that were adopted officially in 1857. An interesting and rare transitional Pattern."

Brilliant Proof.  Ex - Stack's "65th Anniversary Sale", October 17-19, 2000, Lot 1555, "Judd 161, R-4, Bronze, PE" Judd's difficulties with Nickel were repeated with Copper versus Bronze alloys.  This coin certainly appears to be Bronze (Judd 161) rather than ruddy red Copper (Judd 160).
