Hello everyone I found a 1957-d in really decent condition. It looks like it has a lamination error on the reverse. Can I get some confirmation on this. Thanks a bunch for the help Cecilia    |

Try soaking it in 100% pure Acetone and see if it comes off. Definitely some type of substance on it.
Errers and Varietys.

Yes, appears to be a tape issue. As noted, a good long soak in 100% acetone might improve things.

acetone wont affect the coin? Will conserv solvent work?

100% pure acetone is fine. Not standard nail polish remover. I do not know what conserv solvent is. John1 |

I was told it was the only safe thing to put onto coins to prepare to send in for grading  |

It says to use a cotton swab on the coin and blot dry with a cloth on the label, that is enough for me to not go anywhere near the stuff  John1 |

Don't know what's in it so I wouldn't use. If anyone tells you to use anything other than acetone and Verdi-Care on copper, they are wrong.

So I soaked this coin in pure acetone for quite awhile and there is literally no change. Something else I should try?
