Nothing is going on with this coin, it is sitting on my desk at the SortHQ. I have been tinkering with cleaning similar non-numi cents. I dug around and found some commons of similar age/color/and grunge to experiment with. Acetone soaks are not removing this light green stuff from around the edges of Lincoln, the date, etc.
I tried some multiple-day soaks as well and the stuff still does not come off. I did notice that the sheen of the coin changes after a couple days in acetone (long soak). They now look a little shinier than the non-soaked "reference coins" - Extended soak coins have a sort of laminated look (yes, it is clean pure acetone) Just a slight change, but nothing I would dare subject the 1914-D to.
I even tried a gentle rub with a few different things - toothbrush - acetone soaked rag. These contaminants still stick. A harder rub removed some, but not all. And at that point evidence of my dickering was obvious. And even if they did come off with just a gentle rub, I would not dare to rub the 1914-D in any way. I was just curious what it would take to get this crap off.
So bottom line is that I am pretty busy and I need find some spare time to figure out how to safely spruce this up before sending it out. More suggestions would be appreciated! Does anyone on here know of a coin restoration professional? Well, that sounds expensive... I don't want to get too carried away.
SORT ON!!
