1873 Two-Cent Piece. Open 3. Proof-63 RD (PCGS).Featuring bold mint red color and brilliantly contrasting fields, this proof issue is strong for the grade. A touch of magenta patina on the surfaces demonstrates originality, while the strike, often a tad weak this series, is sharp. Only 600 examples are believed to have been struck of both types, with the Open 3 Proofs considered by the Red Book to be Alleged Restrikes. Regardless of their true designation, the 1873 Proof-only issue is a key date for the short-lived but popular two-cent pieces.From The Dr. Andrew Mitchell Collection.
