Ok looking back at the pics I took ya I see why you guys thought it was just flat.
I get it now. But look at second set of photos you'll get it.
As you can see now if the photos as to why I think you are incorrect.
It's not some flat shelf. It's an entirely same or thicker device.
I'm not trying to argue. I'm simply trying to understand.
MD is a small flat shelf that removes part of the device from its original form.
So what happens when the bottom part of the device is just as thick and wide as the top layer?
Or how about in the R where it kind of has a huMp on the curve how would it have that doubled? Would it not only smash it flat and not mimic the hump?

Sorry this it is not an error DDO. Took me some time to analyze all the photos and the thinking of the lines, circles, etc. It is characteristic for double strike small coins for proof on horizontal presses of that time. In fact I never see yet an DDO real on dimes for this year. Could be one somewhere, but at this moment never see. What you has I see before, and it is just surface some kind of grease from strike. We see this also in the modern proof coins. What it is nice with your coin it is the proof quality. In that year the San Francisco change the rules for prepare the proof dies. What mean this, for the first time the dies was polis with diamond paste by the machine then manually with diamond paste. After the dies go too clean process, but some how some paste remain and the coins show this apparently doubling. If you clean the coin everything go away.

Hope help you and the forum.

PS. according with my books I past aprox 12.5 K dimes proof for this year.

I think we need Mike on this one. I am no pro,that said it looks like MD to me as well. There are different types of MD; high bounce, ejection etc. but it is still MD not a doubled die.We need Mike.

given that proof coins are intentionally struck more than once, I can imagine a slight shifting in coin or die between strikes could result in a coin looking like this one

That was my thought Nick.
But what I'm trying to understand is some of it wouldn't cause all like 3 different things going on.
Like silviosi had said would make sense on some of the lettering having that paste under the letters causing them to wipe off persay.
Then you have obvious Machine Doubling going on. Ok I get it some of it is I think where it caught parts of the letters off which causes the device to be thinner then it should be.
But neither explains the U in trust.
Or that R where it has an entirely separate straight leg protruding or the B with identical impressions or the front of the B having only a small fraction of the humps doubling and the center of the B having a much larger spread.
So that's why going with MD just don't fit. To me atleast

This is a high bounce Machine Doubling issue on a normal coins proof die. Note that affected areas are flat. All the affected areas are on the normal sized devices on the outside/inside edges of the devices. Nothing is showing spread or enlargement of the devices. So this is a striking event, not a hub doubling event.

Note on the Variety Vista Listing for that year Proof dime:
http://www.varietyvista.com/07%20Ro...1SDDO001.htm
Note the description:

Quote:
Description: Light spread on date, designer's initials, and IN GOD WE TRUST.

Note the Liberty on this coin? It is not part of the hub doubling description. So that is area is called flat field doubling. What does that mean? Proof coins are struck twice. So if there was any Machine Doubling on the first strike, the second strike would leave the Liberty looking like this coin. This is not part of hub doubling, just Machine Doubling on the first strike of the coin. Only the devices mention on the description area the doubled die areas.

I mentioned this as sometimes it looks like this could be part of the hub doubling, but it is not. Just 'Flat Field Doubling."

Classic MD by looking at the date and mint mark , Machine Doubling can be quite dramatic, on even some of the lesser hub doubling I wouldn't get too excited about it either.

How interesting. Guess that's why they call you the wizard.
Never in a million years would I have thought and Machine Doubling under the first press.
Genious and seriously answers every question I would of had. Thanks Coop for the education.

I'm in agreement, Machine Doubling. I have you have this feeling you do not believe us. More photos are of no use when they are out of colour and way out of focus. Send it in your favourite grading service and be sure show us the label when you get it back. Best of luck to you.

" Machine Doubling will always make the devices smaller." True doubling will have split serifs & make the devices bigger. I don't know how true this rule is. I find discrepancies all over the place in the world of numismatics. Even on the websites of the big authentication companies I've found coins in the image library of authenticated coins with mint marks completely in the wrong spot for the specific die. Looks like MD to me as well. At least on Liberty. Keep looking, I promise just when you're least expecting it, you'll find something great.
