1971D Eisenhower

[silverguy0001]

So I came across this coin in a Antique shop. I found in interesting due to the fact when I look at the side of the coin it does not exhibit the normal copper/nickle sandwich which would be standard for a 1971D Eisenhower. There was a 71S there as well with the blue token that came with them [from what I understand], and upon looking at the 71S, the 71D coin looks exactly the same as the known 40%silver coin. I checked out their other Eisenhower coins that were worn from circulation, and they all had the standard nickle/copper sandwich which is visible from the side of the coin. From doing a little research apparently there were some 40%silver Eisenhowers struck in Denver in 1975-1977 in error, but this coin is obviously from 1971.

I'm in the process of moving so my camera is not in a easily accessible location currently. So no pic yet; sorry.

Any Ideas? The coin is in uncirculated condition. And there is a small nick in the rim. Upon examing the nick with a magnifying glass, I can't discernibly see any copper, or a copper sandwich. This coin has me baffled. Cause everyone says 40% silvers only came from San Francisco.....

Thanks

Weigh it.

Clad IKEs weigh 22.68 grams.

40% SILVER IKEs weigh 24.59 grams.

Will do thank you for the tip

It's very possible a silver planchet could have slipped into the Denver mint. Wouldn't be surprised and if it's real congrats on a big find!

drop it on a hard surface like a wood table and compare the sound to a clad Ike, does it sound the same?

[silverguy0001]

When I flip it or drop it on a table it sounds like a silver coin. I haven't had the time to weigh it yet though. I'll snap a few pics of it tomorrow.

Please don't drop it on any surface, if it is an offmetal coin then you will want to have it graded and slabbed in order to have it authenticated as so. The higher the grade the better for your wallet. Dropping it and dinging it will only hurt your grade potential. If you already know this and feel the need to drop it then by all means do so, it is your coin. I would suggest gloves and a scale for any numismatic coins rather than treating it like a circulated copper cent by using the sound from dropping it test.
