Hey all! Back for more input after the 8TF debacle of earlier this week. I have an 1890 Morgan with a tape mark and some residue from the tape. A couple questions? 1. How can I remove the residue without "cleaning" the coin? 2. How does the stripe affect the condition/value? 3. Any thoughts on its condition...not that it matters much on a coin this common...more curious and eager to learn than anything. Thanks again for all the help earlier this week with the fraudulent '78.
Acetone should take the tape residue off. Pure acetone, not nail polish remover. Just soak it and roll (don't rub) a q-tip over it if necessary.
An acetone soak won't hurt it. Any residue left from the sticky remove with a q-tip as atcarroll sez. Probably have a striped coin though and might want to consider dipping it.
Personally any glue issues on a coin I always started with boiling distilled water first. Then if needed Acetone.
If you have a coin with unattractive toning or some disruption in the look of the toning, careful and judicious dipping in a thiourea/sulfuric acid solution (eZest) can sometimes increase the eye-appeal of the coin without destroying it.
It'll be the nly way to remove the "stripe," as the patina will be different than the rest of the coin even when you do remove the adhesive. And, as a circulated coin, dipping isn't recommended. Frankly, you're stuck. Acetone will remove the adhesive, but nothing short of killing the coin will remove the stripe.
Iz here. The OP coin is a typical crusty coin that once had tape on it for a long time. They don't bring a premium unless in BU with nice color. And a double sided tape toner is even better
It is a mockery of numismatics to see that coin in a righteous holder, and a more damning indictment of PCGS than I could achieve at my most eloquent.
Here's a Peace Dollar I picked up about a month ago with tape toning. Actually the toning is on both sides and is some nice colors. The images don't do justice as to the in hand look. It's a Vam 1 Early Design It's a shame as what didn't come off the area above the Dollar and EPU would probably detail it. It has a nice strike and the colors vivid when you turn it to the light.
On the Morgan... An acetone soak would be good. I doubt if further attempts at cleaning will yield good results. If you like the coin, well and good. If it bothers you, basically your option is to sell it and buy another.
Speaking of peace dollars and toning, here's a nice gold toned one that found its way into my son's collection.
