I'll admit being wrong now, additional scratching at the edge with a pen knife revealed the copper at last. I didn't want to damage the coin in the way you suggested, so I did it my way by picking at it. Consider me humbled.

There is very little void, at some points the core is even with the nickel clad on the edge. This is also the one and only example i've seen of a coin with a missing copper core from all the clad quarters i've dug. If there was indeed corrosion then why don't I see the usual suspect of green oxidized copper leeching out of the coin or even the copper itself? I'm not gonna scratch up the coin to go searching for something that's likely not there.

I was responding to GB. Basically why would I need to scratch deeply when the core is so close to the surface. I took a not so tarnished clad quarter and scratched the rim on a brick and it instantly exposed the copper core, whereas the coin I found yesterday didn't show any signs of having a copper core after scratching the rim on a test surface. My question now is: could this be a counterfeit quarter?

I just scratched it to do an acid test on the rim. But my question is why would it be such a thin layer of copper. These things were made with 75% copper 25% nickel clad in mind, as shown with the other coin of the same year. It's curious so i'm still asking around about what it could be.

Yeah coin shop said it wasn't anything, I had to check myself and it wasn't silver. Still no copper core though which is very strange. Scratching it produced a silvery core instead of a copper one.

Thats the thing though, the nickel clad has been in the water enough to cause it to turn red but there's no copper leeching? I'll need to find a comparable quarter and show the difference. I guess i'll let the coin shop settle it. I'm probably coping with the fact that it's likely a regular old clad quarter

I have found silver coins. Comparing it with the coin I found yesterday it kinda looks the same. Coin I found yesterday looks less grey black though. SchoolofhardNox is right though it's tough to compare via color as corroded silver can be many colors. Top coin standing liberty Bottom coin the quarter I found yesterday

yeah going to a coin shop tomorrow. Also all 1967 quarters I see on google images show the same thing nickel clad with a copper core that is clearly visible with a orange color. This is also seen on the salt water ruined 1967 quarter that I have as well. Something like this, so i'm just not sure about the one I found today as the rim is blackened instead of green/pink.

One last comparison though. I fished out a 1967 quarter from my clad coin stack and a 1966 one. Both are noticeably different from the one I found today with around the same amount of wear. In order from top to bottom 1966 clad, 1967 clad, 1967 something.

It's certainly a strange coin nonetheless, thanks for the input.

top is copper clad and what I normally find, bottom is what I found today. The core also kinda has a chunk taken out of it, and underneath is still black patina.

Not sure I should be taking a wire brush to it. Also here's a comparison between the normal stuff I find and the coin I found today.

I was out and about today detecting my usual spots and I found this strange quarter. Normally when I find coins, I check the rim and give it a good scratch with my nail to expose the copper. This time I found a 1967 quarter that didn't have any of the usual wear and tear found in clad, and it was dark purple sandwiched within, much like the silver coins I've found except this coin has a visible distinguishing line between the clad faces and the inner metal due to beach exposure . Scratching it with my nail did not expose any copper either. Do silver quarters even exist beyond 1964 and if so are they valuable?

Incredible is subjective. I love silver so it's mostly silver! Some gold if i'm lucky! I'm up like almost 30 rings for the year currently at 29. mostly silver some junkers and like 1 gold ring.

Alright alright I might have to increase the sensitivity on my Legend. Been keeping it at 26-27 and it's been doing alright for me. No chains yet though, so hopefully this change will make a difference! The legend has been quite an amazing beginners first detector for me. It's simple enough to learn and operate and the finds have been incredible! It's an adventure every time I'm out there detecting, as you never know what you might find!
