1883 “Cents-less” nickels

The Liberty Head-type nickel was minted from 1883 to 1912.

However, in 1883, nickels appeared without the word “cents” on the reverse. Some of these “cents-less” nickels were gold-plated and passed for $5 pieces.

The Mint realized the problem later in the year and added a denomination.

1913 Buffalo Nickel

In 1913, the design of the nickel was changed to the Buffalo type, also known as Indian Head type.

This new design had two varieties.

The Bison found on the back was modeled after Black Diamond from the Central Park Zoo.

The 1913 Liberty Head nickels were not authorized and should not have been made. Only five examples are known to exist.

In 2007, one 1913 nickel sold for a reported $5 million.
