    A proof doesn't have to have CAMEO to make it a proof....in fact...up untill the late 1970's not many coins had CAMEO....it was rarer to find them....now days its hard to find one without CAMEO...

    Why is that? In some ways I find this coin more attractive than a cameo.

    I mean why the sudden jump in cameo coins?

    It's quite simple, the mint always produced Proof dies with the cameo on the devices. But the cameo effect only last so long on a die before it wears out. And in years past the mint would keep right on striking the coins. Then in the early '70s they changed their practice, and when the cameo would begin to wear out they would replace the worn die with a new one.

    Thanks GDJMSP, Are these kinds of proofs more desirable than cameos to some collectors?

    Hi,
    On the 1941 dime, I would need a better picture of the date. a slightly different angle. Its tough to tell from the picture.

    On the coins with the "extra lines", It is a form of mechanical doubling that is isually caused by what is called die chatter. When a die is a little loose, it hops around during the strike. It shears the metal in unusual ways around the edges of details on the coin. That is what gives it the telltale "step like" appearance.

    On the proof quarter, it is not unusual to see doubling like that as the coins are also subject to mechanical doublings. Being struck more than once as proofs are can contribute to that as well. Also, a die chatter situation can also occur on proof coins.

    Have Fun,
    Bill

    On cameo proofs, they don't replace the dies when the cameo appearance "wears out", The cameo appearance is recreated by etching the die with an acid.

    Not any more Bill, nowadays they use sandblasting & lasers.

    I can only see machine doubling, the serifs on the letters are not split at the tips. Also, the dime shows parallel scratches that indicate cleaning. More experienced opinions will follow.

    Nice to hear from a fellow trekkie! Hope it was not cleaned.

    Hi,
    That is correct Sir! As Ed McMahon used to say. I was answering with the coins he was showing in mind. I shoulda been a little clearer on that point.
    Thanks,
    Bill

    The Mercury Dime appears that it is possibly a Doubled Die, the Washington Quarter suffered mutiple Machine Doubling called Die Chatter and the Franklin Half also suffered Machine Doubling. I believe that the Mercury Dime definitely deserves further inspection.

    Thanks all!

    Huntsman53-- Here are more pics. I dont know what to think:confused: It looks like when it was struck, the die shifted hard right. Is there a die clash by the face? Found a line (gouge?) over the wreath near the axe. And also, would you consider these full bands?

    Please anyone give me some input.

    I can't tell too much from the first pics but it appears that there may be some clashing in the frist pic! The last pic apparently shows a Die Gouge.

    Although there is a slight amount of wear or friction (contact) wear on the bands, they are still definitely Full Bands!

    I would like to see a straight on shot of the entire date. Close and focused. What I see on the shots above is mechanical doubling.
    Thanks,
    Bill

    I dont know, I do not believe its doubled. Like I said it looks like a hard shift.

    Huntsman53-- How often do you find a Die clash on a Merc. ? What else can I look for to verify?

    Hi,
    There is flat , shelf-like doubling on the date. This is mechanical doubling. You can see where the metal is scraped.
    Thanks for the shots of the date,
    Bill
