Removing OLD Tape from Morgan Dollars

Hey I just aquired an old collection of Morgans that was stored in books. Unfortunatly the guy put tape over the Morgans to keep them from falling out of the books. I removed the coins from the books and tried removing the tape and now I have a bunch of Morgans that have tarnish on either side of where the tape was and a hard gluish material from the tape.. Any suggestions on getting the reminants of the tape off?

You no doubt have many worn Morgans that are of common date and mintmark. Why not experiment with dipping them to see how good you are at dipping coins. First try a fast in and out dip, and then rinse. Work your way up to longer dips only when needed. Many of them will still be worth the same even if you mess up a bit. If you develop enough confidence in your skills, try more expensive Morgans. The coins worth over $100 might be worth sending to NCS, certainly any worth over $200.
Dipping circulated coins is never easy, too much dip, and all the imperfections beam out at the eye of the beholder.
You might consider selling all but the coins you really like, and use the money to buy other coins. I strongly suggest PCGS/NGC/ANACS/ICG.
<< <i>What is the process for a "dip" >>
I have no idea, but after you dip them I'm 95% sure the coin is to be rinsed in Distilled water so it doesnt cause spots later on..
btw..
Start experimenting with the low value pieces. I would probably start with a 5% dip 95% distilled water solution. I'd put it in a wide shallow dish so that the depth was not much more that the distance from the edge of the coin to the edge of the tape mark.
Don't dip the whole coin, just the tarished part. And don't just put it in and leave it there. Keep taking in and out of the solution trying NOT to insert it to the same depth each time. (The idea is not to replace one straight line with another.) Keep this up, keeping a careful watch on the color of the dipped area as it lightens, until it is about the same color as the area that was protected by the tape. Where it gets close rinse the coin well with distilled water to halt the reaction. (If the color changes too rapidly for you to monitor it or stop it quickly you will have to dilute the dip solution further.) Repeat the process wih the other side. When both sides are done, do one quick dip of the whole coin to blend the colors, and then rinse, rinse, rinse! I can not stress that enough. Any traces of dip left on the coin will eventually cause spotting or other discoloration.
Wow! I guess I resurrected a 17-year-old post from the ancient archives with this post!
I am about to try the acetone approach (low concentration in distilled water) with the coin (photo attached). It's not a coin that I need for my type set but nonetheless, I'd like it to be as "acceptable" as possible for a previously cleaned coin if she goes on eBay. Are there any "updated suggestions" for this piece before I do the deed? I believe that there is tape (or something) on the shield and the leg area. sadly, it looks like some ill-advised individual did the ole' Brillo Pad deed on the coin previously. What a shame.
As always, thanks!!! Piano 1
Plano, I believe
Acetone is used at 100% strength.
No dilution.
Rinse in hot distilled water and pat dry if not air dry.
100% acetone should get rid of the residue.
The "DIP" is not acetone and it was dip that was recommended to be diluted.
For the original issue, I think I would have tried the diluted dip issue before taking the tape off with acetone, might have made for a better tone transition. For the new coin posted, I would not touch that with dip.
"When they can't find anything wrong with you, they create it!"
Hello and as always, your input to my post is very much appreciated. I will try the acetone today. I think at this point, between the insidious green tape gunk and the "Brillo Pad cleaning scratches" applied by some poor misguided soul, the coin will never be a highly sought-after gem, but it might improve the appearance of the piece. I would like to eBay the coin but if I can relieve Miss Liberty's suffering a bit, then her life may be improved.
Thanks!!!! Wish me (and Her) luck.
