@jas, almost always these are going to be surface staining due to environmental or chemical exposure. Yours looks a lot like some of the dug coins that we see posted here.

Thanks Spence. I've come across a lot of environmental staining but this one kind of stuck out as it actually looks like an old copper penny surface (in person anyways). I'm learning as I go here and been having a lot of fun searching coin rolls lately. Obviously it is hard to tell in pictures, but is there anything specific I should be looking for to compare surface staining versus missing clad? And would something like this, if it was a missing clad error, have any value? Thanks!

All good questions @jas. Not all coins are clad and the Presidential dollars are one such series of monolithic coins. So, there is simply no way for there to be a missing clad layer, such as you hypothetically might find on a modern quarter. One of the best quick checks is to accurately measure the weight--most of the time a missing clad coin will be underweight. Here is a link to help you learn more: https://www.error-ref.com/?s=missing+clad"If you climb a good tree, you get a push."

I'm pretty sure they are clad. They are. Presidential dollar coins are made of a pure copper core with an outer layer of manganese brass. The manganese brass is made up of: 77% copper, 12% zinc, 7% manganese, and 4% nickel. |

All copper nickel coins turn to a bonze color, when given sufficient exposure to in ground burial.

@Jason when you think you might have a coin missing clad layer(s) the first thing to do would be to get an accurate weight to 0.00 grams. That will confirm yes or no pretty quickly.  Below is an NGC graded 2007 Pres. Dollar missing reverse clad layer note the weight compared to 8.1 grams which is normal weight for that coin.  |

Just toning. Manganese brass will turn easier than copper nickel.
