Environmental exposure can be the cause.

It all depends on what the coin was exposed to.
I have some 50 cent coins that are a nice hue of gold on
one side but normal on the other side.

Don't forget about after-market gold plating (not the case on the OP's coins, but certainly one way that quarters might be that color).

This looks like Environmental toning.

Quite a few Bicentennial coins were gold-plated and sold as collector's items. A picture of the edge would be telling.

Probably environmental toning.

Being majority copper, such golden toning on a quarter is relatively common. Really? I had no idea, thanks! Quote:

Definitely not a plated coin - otherwise the edge would be gold-colored too. Your coin is just showing environmental toning as everyone has said.

I agree with others, a light golden toning is not unusual on proof quarters, depending on how they were stored.
This coin is obviously a cupronickel clad proof. However, I just wanted to mention that bicentennial proof quarters were also struck in 40% silver. The 80% silver, 20% copper cladding on the coin faces often tones a light golden color. Just to be clear, this coin is not a silver proof, but that is something to keep in mind, as the bicentennial coins had more options than most years.

Not that there's anything wrong with "decorating" coins, but I have way too much to learn, still, before even thinking about adding another - & non-essential - variable to the equation! |

I rather like golden toned copper nickel coins .
No extra value.

Just to be clear, this coin is not a silver proof... But do you think that this definitely IS a proof? Or just "might" be? Because I've been using the CoinSnap app to help me assess & catalog coins for the past few months as part of my learning process, and although decent, it'll occasionally insist the newest entry is a proof or silver coin, which I've learned to interpret as definitely NOT a proof or silver coin. It told me this quarter is both, so I assumed it's neither. To my amateur eyes, there's too much color on the reeding to qualify for the higher percentage of silver. And although it DOES resemble proofs I've seen in photos, the app's been wrong every time so I've learned not to get my hopes up & to operate under the assumption that it isn't. Plus, I found it in the absolute LEAST likely place I can think of to ever randomly find a proof, especially not one in such good condition: the change machine at a seedy, derelict, 24-hour coin-operated laundromat. |

I agree. It is a clad proof quarter and the colour is from toning, nothing more.

Yup. Somebody broke up a mint set and spent the clad proof quarter. Could have been a dealer who found a scratched proof and just used it for face value change.
