1936 Buffalo Nickel. Satin Proof-66 (PCGS). Fully struck specimen with a soft satin texture on both sides. The surfaces are brilliant apart from a dusting of pale silvery iridescence, and they are as smooth as would be expected for the assigned grade. The scarcer of the two late date issues in the Proof Buffalo nickel series, the 1936 is eagerly sought in both Satin and Brilliant formats. PCGS# 3994. NGC ID: 278X.
