Odd New Jersey State Quarter....

[Lexicon Devil]

So I found this, yesterday, while searching through a bag of laundry quarters. It is not two-toned like a typical clad state quarter, as you can see from the edge. I know they made silver proofs of the New Jersey quarter, but I am not convinced that is what I have here. Did they strike aluminum ones? Or am I lucky?

Interesting. Occasionally the nickel sheathing can completely cover the copper core of the coin. The P mint mark denotes the coin was minted in Philadelphia An S mintmark would likely but not certainly be a silver quarter as San Francisco makes both silver and cupronickel proof coins. The easiest method I have is drop it flat down about a few inches onto a hard surface. Then drop several normal quarters one at a time and see if they all sound the same. A silver coin has a high pitched distinctive audible ring to it. It will sound much different. Note- you don't want to drop rare or valuable coins or even handle them as you can hurt their value but if you found it in change it shouldn't hurt. If it sounds different that's good. Then I would weigh it against a normal clad quarter and see if there is a discrepancy. Keep us posted!

My guess is that you have a state quarter that was chrome plated after it left the mint. I have come across quite a few of those in quarters and halves over the years. It gets the blood pumping when you first see it, but it's a let down.

Definitely plated after it left the mint.

Put it on a gram scale. Looks plated to me.
