I Am Stumped And Need Some Input

    Double Die I know just enough to be dangerous

    I have this '82 Proof (DCAM) quarter that has a 2nd profile and I am certain it is not MD or DDD and ruled out a die break. It looks like an artist's sketch line when doing a painting but not an exact match to the profile. It would be really nice if it were a DDO for a discovery, but I'll take any insight as to what this is????

    I did not break it free so all pics were taken through the plastic, but I'm sure you'll see what I'm talking about.

    Please enlighten me...

    Flat and shelf-like. MD.

    How do people here on CoinTalk always know they are certain? o_O

    I'm not entirely sure what this is, just from these pictures, but I'm not convinced it is MDD.

    It isn't flat and shelflike at all.

    I would also expect any MD to be shiny - this area under concern is cameod just like the rest of the profile. This tells me it is a die effect, before strike.

    I don't think it's really anything at all, just reflecting from the lights.

    No shelf, it's at the same level.
    Not flat and shelf like at all. I've never seen anything like this before. It's like an outline on the inside of the profile.

    Nope, saw it with my own eyes before the pics. There's something going on but don't know what?

    it is a interesting outline...

    Total, complete, and absolute speculation:

    This does not appear to be hub doubling. It doesn't have the appearance of a doubled die.

    This cameo was made during the era of sandblasting the devices. They put a gasket over the coin to protect the fields, and then sandblasted the devices. What would happen if the gasket shifted during this process? I might expect to see some sort of shift or disturbance in the cameo pattern. Could this happen? Did this happen?

    I feel like we need some more experts to weigh in on this one: @JCro57 , @Fred Weinberg , @cladking

    I may have been a little over zealous in my description? More like very confident.

    The answer my be in knowing how many times it is struck to make it a proof surface.. Struck twice ;)

    So you're saying it shifted a bit between strikes? I suppose I could see that. Are there other confirmed examples of this?

    Modern proofs - after 1964 - are struck twice using a special press. One would reasonably expect to see some slightly doubled impressions.

    Examples? I can't find one now. Maybe the coin in question? ;)

    You might expect it, but I can honestly say I've never seen it.

    I have a guess but I think this is one for Fred Weinberg.

    Still curious what your guess is.

    Found a 2nd one in my stash. Either I'm extremely lucky, or these aren't as uncommon as believed???

    Based on the photos, it's a very slight shift between
    the two strikes of a Proof coin - similar to mechanical
    doubling (MD) that we see on circulation strike coins.

    Yes, the shift is a bit more than most that show this effect,
    but it's not a doubled die, and I wouldn't consider it a
    double strike, as Proofs are struck twice anyway.

    I have numerous double struck Proof coins (from the mid-70's)
    that are double strikes, and show a completely different look
    to them, even the ones with close overlapping.
