Jaime Hernandez: The last time the Mint had produced any proof cents was in 1916 when it struck the 1916 Matte Proof Lincoln cents. In 1936, the Mint struck Proof Sets for that year and produced the Lincoln Cent in two different finishes. The first Proof cents were struck in a Satin Finish, while the second finsih was struck in a Brilliant format.
The 1936 Proof Cent with a Satin Finish tends to lack strong Brilliant surfaces compared to the Brilliant Finish which has mirror like surfaces. The 1936 Satin Finish Proof cent is the scarcer of the two coins and there are probably no more than 600 coins that survive with the Satin Finish.
