1957 Proof Penny polished type

A high-grade example of the rare version of the proof 1957 penny. This version was struck in 1957 with dies manufactured in the same way as the 1955 and 1956 Perth pennies. The more common matte type 1957 proof penny was struck in 1959, and shares more similarities with the later Perth proof issues (such as the reverse cameo, matte fields, and sharp rims).
