Definition

• Electrotrial.  An electroformed trial piece. The practice was inaugurated in 1912 by James Earle Fraser who had numerous electroforms (galvanos) made of his Bison nickel designs, both the obverse Indian head and the reverse bison design. These were made outside the mint, by Medallic Art Company in New York City, testing his three-dimensional designs (even silverplating copper galvanos to make them look like copper nickel) before submitting the model to the Philadelphia Mint. He did the same for the World War I Victory Medal in 1917. Numismatic writer Walter Breen coined the term electrotrial, first published in 1988.
