Quarter Size Unstruck Copper Ridded Planchet

SBA coin that the two clad layers have been sanded down.

I had a thought. A quarter punched from half dollar stock...

This example weighed 6.3 grams. Close...

But the missing the layers would make it even less than the 6.4 grams here.

A Kennedy is 2.1 mm thick, the SBA is 2.0 mm, so that would weigh even less.

I don't think most think it's a planchet, but a damaged coin of some sort.

Count the reeds. A quarter has 119, a Kennedy half 150, a Susan B. Anthony dollar has 133.

Those reeds are fat and flat, which suggests to me that they might have also been sanded to some degree.

Coins can be shrunk in a variety of ways, including acid and electricity. To me, this looks like the faces got sanded off a cupronickel clad sandwich in preparation for making a medal, love token, or decorative piece.

I also wouldn't rule out a 40% Kennedy silver half dollar that had the silver stripped via a chemical process, then the leftover copper medallion was worked on in the shop.

makecents , sorry it took so long to get the pictures requested , pic#1 planchet over quarter Pic#2 planchet rim reeded is on the center , pic#3 shows quarter under from the side , pic#4 quarter over planchet , They have the same diameter.

To be clear, this will not help if the blank was punched from the wrong stock, since the coin would still be struck and reeded as normal.

But...
...Counting reeds may be helpful here.


I doubt it came from a 40% silver anything. The core is 20% silver, which is enough to look grey compared to the red/brown of pure copper.
