2009-S proof half dollar doubled eagle head 2 2

[Hinkle]

On proof coins would this be considered doubling. That actually has the shape of its head on top. Or is that something else going on. Hmmm

Boy. That is weird. Idk if that's Doubling or not. Proofs are so difficult to see in print, especially when they are from a special set. Could it be Frosting Slop or something like is on Washington's Head on the Crossing the Delaware Quarters? Anyways it isn't right, that's for sure. Here's a ScreenShot of the example given on USS CoinBook and there's clearly nothing like that on it.

Hi Karen, glad to hear you're back. Yeah kind of interesting,  I don't know anything about proofs but something not right going on. I sent this coin in yesterday to have it looked at. I just know if they have it in hand they can tell me more about it. Soon as I get the results back I'll post it on here.

Maybe we all can guess what it may be, that would be alot of fun. But here's a pic that I pointed out a couple of things that shouldn't be there.

Got the results back. Flate doubling, cool to know proofs are double struck. Well I know a little bit about proofs and how there minted. I want to thank everyone for taking time to look at this thread. One day I'll find something very cool, but got to be patient and keep hunting.

Modern era proofs are struck twice in presses designed to keep the coin and dies in alignment....but, shifts can occur.

Some proof coins in other Countries are struck up to four times!

Some “tour struck” non-proofs too. The “strike your own coin” option at the British Royal Mint. All are struck four times.

So, strike doubling on the first strike, which was flattened by the second strike, which also had strike doubling, causing tripling of the design. Interesting, if not very valuable.
