Query - Real Morgan ?

Need picture of reverse, weight and diameter and if it's magnetic.

The greenish corrosion makes it look suspect.

Weight and diameter and magnetic?

I suspect it's a silver plated copper fake.

From what i can tell, the coin has been cleaned. Weight is okay for a circulated coin. We need info on thickness. 1878S is a pretty common coin, so i will not count it off as a fake even though it has some verdigris

Thanks guys for your help. I aaked bcoz im.a newbie, got an 1878s and 1921D in a local auction.

They both look real to me. not verdigris, just toning.

Here i tried to maximize a detail of picture 1, coin should have a reeded edge, but I cannot recognize one.

Absolutely genuine, 2nd reverse. Simply a hoard coin which were stored at the San Francisco mint for decades that were released by the millions in the 1950's and 60's. One of the most common dates of the Morgan series to be found in MS condition such as your example.
