German Silver or copper-nickel with central perforation J124B & J124D/P140. with less than a half dozen known. This used to be J152 & J152B respectively in earlier editions. Nickel without central perforation J124C/P141 which is the most common of these with about a half dozen known. This used to be J152A in earlier editions. Copper without central perforation? J124E/P142 with 2 confirmed including the Parmelee, Byron Reed example in the Durham Museum. The Parmelee sale calls them cents not ring cents thus it probably is not perforated.
