Although described as regular dies trial pieces in the literature, it is more likely that these were deliberately struck for sale to collectors. Examples are known as follows: Copper J554. This is unlisted in Pollock. If any do exist, they are probably masquerading as a regular issue proof. Copper-nickel J555/P616 with only the Brenner-1914 ANS exhibit piece mentioned. Nickel J556/P617 with only 2 or 3 believed to exist. Oroide J557/P618 with only the J.E. Drew piece mentioned. Photo is of the former J.E. Drew piece.
