I have multiple examples from same 1000 coin bag with the exact same raised areas on each coin.
Was it rust on the die??? Other thoughts??

    Clearly some type of die defect. Whether it came that way, or deteriorated, I can only guess.

    Interesting what you can find when you look closely. I have a bunch that look struck through paper. The pattern changes as the debris moves around and falls away.
    Give Blood (Red Bags) & Platelets (Yellow Bags)!

    Looks like a pitted or rusted die.

    Are you talking about the mechanical doubling on the letters?

    No not the mechanical doubling.......the multiple raised areas that look like buckshot.

    I hate to say, but some rats pissed on those in the back room in the mint before they were shipped to you. Also the raised area you are talking about is the heat and rat pee doing a job on the alloy. Just my opinion you can go wit it or stay away and keep playing guess it.image

    I just seems odd that a die would have so many pits/defects.
    Not your usual gouge, polishing mark, scratch etc.
    I don't know if it was in the original die blank or something that happened after the die was made.
    Again this is not something on one coin but it is on multiple coins in exactly the same location and to same extent.
    Obviously on the die not on the coin or coin blank.

    I've not seen much of this but have to suspect defective steel.

    Modern die steel is extremely high quality so this should be very uncommon. Most
    of this kind of metal goes through a continuous casting now days and it's possible to
    gets voids in the metal. These are small enough that XRays might not have detected
    them. The technician might have overlooked them or thought they'd press out.
