This is an obverse electrotype trial piece, in white metal, by James Earl Fraser who is known today as the designer of the famous buffalo nickel which was to be in circulation from 1913 to 1938 and on patterns like P1789/P2025.
It shows a head of liberty but her coronet in not inscribed. It looks similar in some ways to Charles Barber's famous design used on regular issue nickels from 1883-1913 and on patterns like J1690/P1892 but is far less refined.
It appears to be unique and was part of the Fraser estate and sold in Bowers and Ruddy's 1981 ANA sale.
