rexvictor Valued Member United States 115 Posts	Posted 11/02/2011 7:27 pm Hi BadThad, Thanks for your reply. I feel comfortable trying the distilled water, however I don't think I'm up for the solvents. I've read that acetone can have an effect on the surface/toning and that the materials it dissolves can be redeposited on the coin as it is removed from the solvent. Is any of this true, and if so, how is it to be avoided? Thanks for pointing me in the right direction. If anyone has had experience with NCS with this type of job, please chime in on how it all turned out! Report this Post to the Staff

Acetone will not harm the metal surface or patina of a coin. However, acetone can potentially reveal discoloration underneath a surface coating. The patination on your coin is fairly uniform so that should not be an issue for you. After you soak a coin, always rinse with fresh acetone afterwards to remove any residual residue.

rexvictor Valued Member United States 115 Posts	Posted 11/03/2011 11:22 am Thanks Freedom and biokemist6! So far, I've done the following to the coin: Soaked in distilled water for three hours Rinsed with acetone Soaked in acetone for 5 minutes Rinsed with water and still soaking (will go at least 12 hours) I will repost with fresh pics. There's more red now coming out, but the difference isn't huge yet, but it's a definite improvement! Report this Post to the Staff

There is no need to rinse with distilled water. The fresh acetone will completely evaporate without needing to rub, dab, or wipe. One cannot say the same of distilled water. They key is the fresh acetone rinse, as the soaking acetone can leave residue as mentioned above.

rexvictor Valued Member United States 115 Posts	Posted 11/03/2011 7:59 pm Thanks for the tips, everyone! I'm back with some pics to show the results. I had to resort to the ANACS-recommended rolled q-tip with acetone method for some stubborn spots. It's a definite improvement, though I was expecting a more dramatic result.

BadThad Bedrock of the Community United States 19952 Posts	Posted 11/05/2011 03:16 am Looks like it is less glossy. Do you think you got it all off? Now I see some light verdigis around the hair. Do you have any VC? Lincoln Cent Lover! VERDI-CARE™ INVENTOR https://verdi.care/ Report this Post to the Staff
rexvictor Valued Member United States 115 Posts	Posted 11/05/2011 12:24 pm Hi BadThad, Yes, it been through VC and very lightly rubbed with microfiber. I think it is just a combination of the patina and a bad picture. I had to resort the the cellphone camera for this close-up, but it is pretty accurate (discount the noise in the image): Report this Post to the Staff
