100% pure acetone might help some.Do not use standard nail polish remover.

acetone will help remove the tape gunk, but the weird toning will likely remain.

Sorry, but these base-metal coins cannot be readily cleaned. Any actual tape still remaining on the second coin will come off in acetone, but the dark colouration will remain. The third coin is, unfortunately, corroded and damaged.

On the second coin, it seems to me that the environment has eaten the top layer of brass.
