First post here and a novice, so I just want to make sure that this is machine doubling. Can someone help me out with this? This is the first time I've taken a loupe to my proof sets. I know the case can easily make it appear like there is doubling, but I assure you I have compared it with all my other proof quarters. It is tough to photograph through the case, but there is doubling on all letters. It is most obvious on Quarter Dollar, but I can only get good shots of the split in the As. There is doubling at the top of Liberty. The IGWT in my photo has some light issues, but I'm pointing to where I'm seeing raised metal. It is the same on all letters. Thanks!
I know it's difficult to photograph proof coins that are still in the holder, but unfortunately it's impossible to tell by these photos. I'm leaning towards strike doubling.
The proof coins are struck many times to put the nice heavy design on them. sometimes the different strikes can be off set a tiny bit between strikes and we call this machine or strike doubling and is not worth very much.But don't go by what i'm saying if you think it is a doubled die get advice from a error examiner.
Proof blanks are specially treated, hand-polished, and cleaned to ensure high-quality strikes. The blanks are then fed into presses fitted with specially polished dies and struck at least twice to ensure sharp, high relief. The coins are then carefully packaged to showcase and preserve their exceptional finish.
