Strike doesn't seem to be much different.
I thought with all the pressure on just the copper core it may
show some distinct characteristics not present on a normal strike. Because copper is relatively soft.
"Dual missing clad layers are rare on all U.S. coins, with less than a dozen examples known for all U.S. coins combined!"

 

I cant help but think something besides environmental wear is the cause, the more look at it the more it looks odd, notice how thin and not as round as a regular quarter(I tilted it sideways a little just show the different in size)

 

Have you weighed your coin? If it weighs anywhere in ball park of 5.67g it's a quarter. It's almost never missing both sides of the clad layer. That coin would weigh around 3.75g.

 

What would cause a coin to be that much skinnier and smaller than a regular quarter?

 

i do not, but the weight is lower, and the coin does have some strike "weakness" on the reverse (dime) this is why i am asking...

 

What? what are you talking about?

 

sorry, ws researching my dime and thought i was on my original post, that was a mistaken post on wrong forum sorry padd!!
