can anyone help: are there any known issues with the 1967 reed GW quaters? Copper is sunken & nickel edge is higher forming a channel in the reeded edge. See attached

to CCF. I believe that is caused by acid eating away the copper,no added value just PMD.

Even the small quantity of phosphoric acid in most soda pop is enough to selectively erode the copper over the copper-nickel.

I am still interested to see what others may say, but that would be my guess, acid.

I agree - I see dimes and half dollars like this also, and they appear corroded.

Again thanks for the info from all

The entire surface of the coin is in pretty rough shape also. I'll go with corrosion of some type.

So much to learn! So little dime!

Could be from being dipped in acid.
