Fort McHenry quarter with a silver side and a gold side

[kzdeaguero]

I am just wondering what this is, one side I gold and one side silver

In my opinion, its either a coin which has one side with toning, something that happens and quite common. The other is a possible attempt at electroplating. A few others is some sort of chemical reaction, stained or other condition..

Look at the obverse of coin where IN GOD WE TRUST. Whatever this is, it also bled from the reverse to the obverse. Have a look at the reeded edge and see if the gold color is there. See if it affects some or all of the reeded edge.

On the reverse just past the word McHENRY, some of the goldish color has come off, exposing the normal color of the coin.

Weight of suspect coins is vital. It will help assess what the coin might be. Scales which display down to the hundredth of a gram is better (#.## g). If the coin was electroplated, the additional metal is so thin that it should not affect the weight too much. The weights of the us coins has a tolerance range, and its best to have a chart handy as weight of a coin is not an exact science.

Thanks for your thoughts, I don't have a sensitive scale, but I thought about that also, it weighs like a regular quarter. I was thinking maybe it was like at a shop or on display somehow and this only one side was and turned gold. I appreciate your input
