    You may be seeing burnished material from the tops of the damaged devices. That could explain the zinc we are seeing.

    Yea that’s what I was thinking
    I know the metal above the devices came from the devices at the tops of them.
    But how no damage down to the physical raised metal GOD but above is the metal from the devices.
    I took up close images dither in this post if you scroll might find them.
    I was thinking from ejection or getting ejected slightly early from storming chamber but no damage made me rethink.

    Got an opinion of it being slide doubling. Interesting how it occurs hadnt hewrd of it before. “In this form of doubling, a die drags itself through the newly-struck design, smearing the features. Strong cases of slide doubling are always restricted to the face struck by the hammer die. After reaching the lowest point of its downstroke, the hammer die shifts to one side without bouncing. As it drags itself across the newly-struck design, it piles coin metal into a series of ridges.” Link below to error ref.

    Nothing close to split plate doubling.
    Not an error but cool to see something that occurred during the striking process and a term for it as well.

    Considering that it is a Zincoln, that opens up such a can of worms, it might be anything. I'm just waiting to see what others say.

    Possible and makes sense slide doubljng.
    In short the die drags itself through the newly-struck design, smearing the features/dragging them away from the devices. my post above yours too I posted a ljnk

    I saw the first photo and new it was zinc. It’s a worn die issue.

    Same well not a die issue and by that I’m assuming die deterioration is not the cause at all for the slide doubling to occur

    It's a form of split plating doubling. I wrote about it many years ago in my Coin World column. Here is the relevant paragraph: "These tiny letters of exposed zinc could be explained once I realized that split plating doubling actually involves two sources of stress. In addition to the tensile stress mentioned earlier, there is direct physical trauma from the copper plating snagging on sharp edges located at the margins of recessed design elements in the die face. At periphery of the obverse face, the copper plating sometimes tears as it catches on the small posts and corners of the sunken letters of IN GOD WE TRUST. Rounded letters like O and G have a central post, while angular letters like T have two sharp corners at the junction of the crossbar and vertical bar. When the copper plating snags on these sharp edges it rips open, producing small, letter-shaped areas of exposed zinc."
