How To Tell If A Coin Was Struck On A Dime Planchet

tmundy, your coins are from the war era. In 1943 the cent composition was modified to zinc plated steel to conserve copper/bronze for the war efforts. They should be magnetic attracted by a magnet, if not then that might be worth investigating further.

In 1944 and 1945 the used brass retrieved from the war efforts was brought back to make coins or cents again. Some history value.

Will add uncirculated condition and or varieties can add value, but nothing stands out with in the current image. Thanks, Doug.

PS: also probably should've started a new topic, but don't see anywhere that the OP ever updated this with their own coins images.

edit: to fix wording above.

These are called Steel Cents. To CCF!

I have thousands of coins struck on dime planchets .....

All of them are dimes.

I do have two quarters that are struck on dime stock, those are under weight.

I don't believe you are seeing rims. I think what you are seeing is the coin in an older PCGS slab that had the soft gasket which is rolling over the edge of the coin. That was one thing I didn't like about their design, the gasket obscured the edge and often the rims of the coin as well. The circular cropping of the image just makes the problem worse because you can't see the gasket so it looks like what you are seeing is the rim.

Yes I know, old thread, but there was a question in it that wasn't explained. And it is recent enough that the early participants may still be interested.
