PL and DMPL vs Plating

    Ok everyone, I took images angling a 300 lumen light on the coin then turned the photo saturation way up.

    UNFORTUNATELY...There are hairlines in the fields and her cheek... but the weird thing is there's nothing on the devices like her weirdly reflective hair. And the back is filled with polish lines. Here is the saturated image.

    Would anyone like to see close ups if anything? I'll take one of the reverse hairlines.

    Is it possible that it is just overdipped, but the luster ridges were not completely eaten away?

    @TypeCoin971793 when you say dipped what do you mean. I always assumed people meant dipped in some silver coating or something. But recently i've been wondering if people mean dipped in acetone or some type of solution?

    I’m not typecoin, but acidic thiourea solutions is usually what “dipped” refers to. You should do a forum search on this as it is a whole big can of worms that had been covered extensively. :)

    "dipped" is when a coin is stereotypically submersed in a coin cleaning solution which varies depending upon coin. But some names are : ezest, speed dip, verdi-care, MS-70, coin care to name a few. When used carelessly it can strip away the surface (luster) of a coin, can leave a blast white surface, clouding. If not properly neutralized/removed it can after some time turn black.

    Stuff like that.

    "plating" is different where some silver or gold coating is added to the coin to make it look nifty to an unsuspecting buyer.

    Could we get some more input from others? If you know someone that might have some input please tag then.

    So far we have this information:

    -Hairlines in field and cheek with extreme image saturation but not visible with naked eye.

    -No Hairlines on any other devices, especially not in the weirdly shiny hair.

    -Luster remains on all if coin

    -Heavy flow lines visible

    -Die polish lines visible

    -Non reflective devices on reverse, non reflective letters on obverse.

    Questions I still have:
    How can the whole bust be so reflective but the hair doesn't have Hairlines?
    I don't think it was dipped, or why would all the devices not be as reflective?
    Why is the eagle not reflective but bust is?
    What could shine a coin this intensely without ruining flow lines, luster, and polish lines?

    I know we can't answer these for certian but I'm looking to build answers and theories to help learn more about this coin and others like it that may follow.

    I think I've just come to the conclusion it was cleaned then dipped. There hasn't been any more input so i'm not sure what else it could be. I don't know who was dipping coins so long ago that it was able to develop such a thick layer of crud on the top. Either way cleaned somehow. Thanks for the input everyone
