A coin struck on a planchet intended for another denomination or of the wrong metal is known as a wrong planchet error. They're very rare in this series, with approximately ten believed to exist. They include 1863, 1864-L, 1868, 1893, 1900, 1905 and 1908.
The 1869 imaged below was struck on a Seated dime planchet. Note that the planchet is too small for the larger sized Indian cent dies.
