2000 Gold Tone Manganese Quarter? Baffled But Excited

I washed it with soap and water.

Please post a photo or two of the reeded edge. There's a possibility that the coin was plated. There have been third-party vendors who've 'gold' plated quarters and sold them in sets.

Eager to hear what others have to say.

Agree with Bobby. These were sold all over (especially on late night infomercials to old people) back when the State Quarter series began. They would plate them in a microscopic coating of gold, then advertise them a "24k gold quarters" and sell about a dollar face for $19.95.

Never never never wash or clean your coins. It destroys the patina and value!

I also agree this is a plated coin.
Very common I'm afraid.

to the CCF!

I won't rule anything out with turn of the millennium.

very well could be plated, and it is a Denver mint, not Philadelphia, but, Who knows, they were playing around for dollar planchets with quarter size stock in odd alloys at the end of 1999 and beginning of 2000 and testing strikes. Some have turned up.

still could be plated, because plating is pretty common with those.

The weight for a quarter should be 5.670 grams give or take, but this won't be difinitive either, because I can't tell you what the weight of the experimental planchets were and a layer of plating is minimal additional weight.

Clear in focus pictures of the coin, front, back and edge would be helpful, and still it might not tell us. I'd say you could scrape between the reeding on the edge (least noticeable spot for a test to happen) with a razor and if it's plated, it will come off and show copper, but I'd do less invasive methods first before going that far..

It's one of those things where it's going to be 99%+ plated, but that year has a higher chance than usual of being off metal and struck on an experimental planchet.

Don't get your hopes up though. It's had 20 years to circulate and be messed with and likely not a rarity.
Just telling it like it is.

I don't think weigh will be conclusive though, for all I know the experimental planchets were within Weight Tolerances for quarters also.
