The lines appear to the left of Liberty's face but they also show faintly on her cheek and hair. Is that a lamination? Thanks *Edited by Staff to ad image to post* Report this Post to the Staff

coins888 New Member United States 3 Posts	Posted 07/13/2010 06:44 am These lines to the left of Liberty's face are in a region that appears lower than the surface of the coin. They don't look imprinted in some gunk or crust on the coin's surface. Report this Post to the Staff

That may be a separate issue - gold being as soft as it is, I think that whatever it was glued to gradually impressed itself upon the coin. Report this Post to the Staff
biokemist6 Bedrock of the Community United States 12437 Posts	Posted 07/13/2010 10:44 am I am not seeing any lines outside of the discolored area which leads me to believe that the textured pattern is only on the glue and not the coin. Glue has a bad habit of creating optical illusions on coins, people think they have all kinds of odd things going on like latent patterns or extra metal. Start by soaking the coin in water. If the glue is water soluble, it will come right off. If water does not work, then the use of an organic solvent such as acetone should take care of it. Acetone is flammable but can be safely used with a few precautions(away from all ignition sources, well ventilated area) and it will not harm the coin at all. Report this Post to the Staff
