JohnK83882 Posted February 25 #1 Posted February 25 Found one of these guys in a pile of stuff that just came in. Then I fished around and found a mate for it with the same design, a brass disk but with a steel insert with pins. Not seeing any mentions of type Vs with steel inserts. The clutches are post-WW2, of course. With the steel parts and the fact that the disks are flat and without maker marks, I'm assuming the disks are mid-WW2 make.
JohnK83882 Posted March 16 Author #2 Posted March 16 Here's another steel back. This one is fully steel in the back and had a dimple.
QED4 Posted April 22 #3 Posted April 22 There are early Type V discs made during WWII to save brass also why they are thin stamping rather than the earlier solid discs. I believe the backing is zinc not steel. Once the restrictions on brass were lifted they were made of all brass and eventually back to the solid ones.
JohnK83882 Posted April 22 Author #4 Posted April 22 I'm sure some were zinc but I checked and this is magnetic so it's steel.
268th C.A. Posted April 22 #5 Posted April 22 Zinc is attracted to a magnet. The 1943 one cent is the only US coin ever made that is attracted to a magnet.
