The regular dies trial piece. Examples are believed struck from both the 'Small Motto' and 'Large Motto' obverse dies as follows: Large Motto Copper J370. This was delisted by Pollock as being virtually indistinguishable from a regular bronze piece. It is likely, however, that some exist. Copper-nickel J371/P440 with over a dozen known. Metallurgical analysis is recommended as oddly toned regular proofs could be misattributed as one of these. One of these is known on a broad 144 grain planchet which has been misdescribed in Judd and Pollock as a J364/P438. It is now listed as J371A. It is ex Brenner-1914 ANS, Pine Tree 9/74 where it is illustrated and shown to have the regular reverse. Aluminum J372/P442. This is believed unique and is also in the J.E. Drew collection ex Loye Lauder, Egbert. Nickel J372A/P441. This has been described as slightly magnetic and is listed by Pollock as being in the J.E. Drew collection ex B/R 1/75, Hughes 10/80. Small Motto Copper J373. This is unlisted in Pollock. If any do exist, they are probably masquerading as a regular issue proof. Copper-nickel J374/P436. This is unconfirmed.
