Another Restoration / Contamination Question

Post by UncleGildy » Fri Feb 15, 2019 1:54 am

Hey - Russ started it, with that cool restoration success story, and then Chris pulled me in with an interesting toning question. Now I have to ask for help with my 84O VAM-19A. (I labeled it v32A, but less than a year later Rod had to set things straight and I see it's now a VAM-19A :o).

Can anyone tell me if this stuff is a known type of toning or contamination? I love cracks and break of this VAM so much I picked it up in spite of the possible contamination.
Any opinions on the grade would be welcome too.

Felt so bad about the photo's lighting, I jazzed up the contrast in the region of the break.

I agree, it looks like something acetone could take care of.

Thanks guys! Would this be localized treatment with a wet Q-tip or better to submerse the entire coin in a glass tray will with acetone for a period of time?

That's tape residue. A wet swab should loosen it up. Just don't rub the coin, especially since the swab will dry out quickly.

I have a can with acetone that I drop a coin in and just close the lid and come back to it days later. That way the acetone doesn't evaporate and it soaks into tape residue and removes it.

Tape residue, hm... That's interesting. It is the color of the 'glue' component of old, aged scotch tape, and old, yellowed envelop glue. I wonder what kind of tape it was and how it got there?

Thanks for the helpful info and great advice. I think I'll try that soaking in a can for day or two so I don't cause damage from being a klutz.

Putting tape over a coin has been done for awhile now, if a coin has tape on it the coin cant really get scratched from laying around in a draw somewhere.

Yes , glue residue from tape. Russ is right. Put in a jar or container of acetone and let it sit.

Well, it is an old coin. Probably taped into a birthday card back when it was just a dollar.

..."just a dollar"?! :o OMG! Oh, that's right - I forgot how things have changed, and my focus on coins differs a bit from the rest of the normal world.

Reminds me of Nashville last summer, when I ran across this silver dollar convertible - a customized '64 Bonneville, owned by Webb Pierce, which had "350 authentic U.S. silver dollars embedded in the interior". The sign next to the car revealed that in 1978, he had them replaced with "alloy" silver dollars. Makes you wonder just what the originals were ...and just what kind of tape they secured them with ;)

Most people were focused on the cow horns on the hood, pistols for door handles and shifter that was integrated into a saddle. Cool enough, but there were 350 silver dollars were all over the interior!

Thanks everyone for the info and advice, I'll clean her up in some acetone this weekend.

Interesting timing. Had he waited until late 1979 or early 1980, he'd have been popping coins off the dash at $30 each, melt. Hopefully, he waited until then to sell them.

Here are the results after about 30 hours in Acetone. I used a small glass jar rested at an angle, so the coin was in contact at only 3 points along the edge, and the main coin surfaces had access to free flowing acetone (I didn't want it resting on the middle of either surface). I refreshed the acetone half way through, lightly dabbed the bad areas with a cotton swab while submersed in acetone and swished it around a couple times.

You can still see a little coloring in the residue areas, but I swear it seems more like toning now. Here are the new LFCP's.

I'd say it was a great success, and the reverse looks a lot nicer too.
:!: Most importantly, the luster and appearance of metal flow in the surface do not seem altered in any way. Thanks again for the help and advice.

btw - I was going to post my pic of the VAM mobile as it exists in 2018, covered in Ike dollars but didn't have the heart. Better to remember it with Morgans. :)

Switching from Morgans to Ikes is to the eye as switching from Big Band to disco is to the ear. Better to be blind and deaf. No offense intended to our 34th president.

Glad you gave it a shot. So many are afraid to use acetone because they have heard the “never clean a coin”, not realizing acetone just lifts gunk off without abrasive ness or lifting part of the surface with it.
