The regular dies trial piece.
Examples were struck as follows:
Silver-copper J407/P477 This is an experimental piece using the regular two cent dies struck on a planchet containing both silver and copper supposedly from native Michigan ore.
Most examples show primarily copper with streaks of silver.
About a dozen or so are believed to exist.
Additionally, off-metal trials were also produced which were more than likely deliberately made for sale to collectors as part of complete off-metal sets.
Copper J408. This is unlisted in Pollock. If any do exist, they are probably masquerading as a regular issue proof. Many of these or the regular bronze issue have been silverplated and were listed as J409B in earlier editions of Judd. The reason for the silverplating is not known.
Copper-nickel J409/P478 with fewer than a dozen known. These were struck using the Plain 5 obverse die and are known married to 3 different reverse dies.
Nickel J409A/P479 with fewer than a dozen known. These were struck from the fancy 5 obverse die.
Silver J409B/P480. This is unconfirmed and now delisted in the 8th edition of Judd as they appear to be silverplated copper examples of J408 including Lohr's and 2 in the Eliasberg collection.
There are listings for silver coins including H. Chapman 5/29 and Stacks 1939 ANA which we believe to be silverplated examples. If a true silver coin does exist, it is likely a mint error struck on a quarter planchet.
The illustration shows 2 silver-copper examples. The top one featuring silver on the obverse side is the Byron Reed Coin.
