vermontensium Moderator United States 16679 Posts	Posted 04/10/2009 11:48 pm I know BadThad sells verdigone but I am wondering if there would be another way to spot remove (possibly dabbing with Q-tip) verdigris from the rim of a Lincoln Cent This coin has the usual organic grime in the devices here and there but, it's the verdigris I'm concerned about.

vermontensium Moderator United States 16679 Posts	Posted 04/11/2009 6:03 pm Here is the pic of the rim verdigris: I know it's not bad but, I'd like it gone I know it looks black like carbon but in hand, it's mint green. swcoin.ecrater.com Edited by vermontensium 04/11/2009 6:05 pm Report this Post to the Staff
just carl Bedrock of the Community United States 20753 Posts	Posted 04/12/2009 09:34 am For such a small spot I would suspect that a q tip dipped Acetone may work a little. Dip in Acetone and lightly rub that spot. Or just dip the entire coin in some Acetone. However, from what the photo appears it is already going to leave a mark there regarless of the removal of that spots substance. Report this Post to the Staff
vermontensium Moderator United States 16679 Posts	Posted 04/12/2009 10:30 am Thanks Carl. This is the largest spot on the coin. Like I said, the obverse devices have your basic organic matter which isn't much really, and the reverse has a little organic matter as well. I'll probably just dip the whole coin in Acetone however, BadThad has suggested Xylene as a better solvent for removing organic stuff. swcoin.ecrater.com Report this Post to the Staff
pls Rest in Peace United States 1729 Posts	Posted 04/12/2009 9:40 pm I've used GooGone and a toothpick with great success for removing organic gunk as well as gum and other unidentified substances from common foreign coins. It also removes some of the verdigris that I've encountered without altering the patina under the coating, although if it has been gunked for a long time, sometimes the original, shiny surface emerges next to the current patina.

I may be wrong but from your photo it does look like there will be a pot type mark where that spot is located. Hopefully I'm wrong and nothing will be left there. Report this Post to the Staff
vermontensium Moderator United States 16679 Posts	Posted 04/14/2009 8:29 pm Yeah, I am going to do a "before and after" photo. Under a loupe, looks like just surface verdigris. No signs of pitting I hope I'm right. swcoin.ecrater.com Report this Post to the Staff

xshift Pillar of the Community United States 2669 Posts	Posted 10/19/2009 3:57 pm I was wondering where that one went.. I never saw the end of that one until now... wow We may need a sticky of some sort - conservation vs. cleaning and what NOT to do to a coin. I find it mind-boggling to read posts going from 'blowing' to 'dremel with a wire attachment' in one fell swoop. Verdi-gone has proven to be mild-mild-mild. It doesn't do it all - that's not what it's for - but it does take care of quite a bit that used to be attempted with harsher methods. I hope it's something that becomes a staple in our numismatic diet oldmismatist, BadThad here on the forum is the creator. You'll need to stick around a while and do at least 50 quality postings before any talk of buyin' or sellin' here.. And Welcome to the forums! Vermontensium, did you get those before and after shots so we can see how yours turned out? Report this Post to the Staff
chequer Pillar of the Community Canada 4227 Posts	Posted 10/19/2009 4:07 pm I'd love to see a before and after shot too, Vermontensium. Yeah, that other thread was something. I'm trying to grasp the concept ... perhaps I'll try the acetone dip, nah I'll whiz it! I'm glad the thread is there to try and teach others. Report this Post to the Staff
