This is a muling of the reverse dies used on J111/P125 and J112/P126.
Presumably these are restrikes made later than 1849.
Examples exist as follows:
Silver-copper J113/P127. These are more likely standard coin silver as opposed to being 50% silver, 50% copper as on J111/P125 or 60% silver, 40% copper as on J112/P126. Pollock shows weights which for the most part match show them to have been struck from standard half dime planchets. About a dozen are believed to exist.
Copper-nickel J114/P128. It these are 75% copper, 25% nickel then they would be mid 1860 products. Fewer than a dozen are known. The Pollock book notes 6 known but to this must now be added the Eliasberg and Pittman examples.
Copper J114A/P129. Only the one offered as part of lot 1738 in the Farouk sale is known.
