    Hello all,

    I purchased a box of slabbed U.S. coins, from Lincoln cents to Susan B. Anthony. There were 40 slabs in the box but there are 9 that has a hard substance on the reverse. The slab is not damaged, something is stuck on these slabs. The Roosevelt I have pictured is like the other 8. The obverse is good the backs are not.
    So question, is there anything that could be tried to take the substance off. If not what would be the next actions ? Again, the slab has not melted I was able to scratch off a little but to do that would take forever. Thanks for imput. dime front.jpg dime damage 1.jpg dime damage 2.jpg

    If it's something on the plastic like tape residue?
    Maybe try 409 or wd40 on a small spot.

    I tried 409 but no good, the WD40 was a thought, how about Goo Gone ?

    It's like they were placed against a plastic or rubber and then stuck together.

    I would try GooGone. It works for me. Use sparingly.

    Could try pressing masking tape to it. Then pull off slowly on an angle.

    Pulling off with duct tape...use a cotton swab and 91% rubbing alcohol and try the duct tape again...

    A number of things may remove it but they will also damage the plastic.

    Looks like bubble wrap/u-v?

    Looking again it will cost you to have the slabs replaced. Depending on the coin and it’s value it may or may not be worth the time and the cost.

    each is worth about 15 bucks each not worth getting them reslabbed.

    I use Turtle Wax lens polish on all my slabs. I do it to polish out scratches but it also removes dealer sticker goo as well as the reverse hologram (oops)…. Stuff is cheap. I’ll never need to buy a second bottle. It’s worth a shot anyway.

    Lemon juice???
    Dawn dish soap???
    Something non abrasive I'd say.
    Whatever you use, probably better to keep it off the labels.

    Be careful.
    I believe 91% alcohol "melts" plastic.

    Try the 91% alcohol on 1 spot, see if it works. If it doesn't, I can't think of anything else that would, that would not damage the slab itself.

    My response was based on watching some people installing a computer fiber network years ago (good grief, that must have been back in the 1990's).
    They'd polish the fiber ends with a device that used alcohol on a VERY fine-grained plate.
    I always thought the alcohol facilitated that process by making the fiber easier to deal with.
    But now that I rethink the process, maybe the alcohol was just there to wash away the debris from the polishing process.
