skyshark124: I 100% agree with you. I will probably end up dipping it after getting familiar with using acetone and testing it on other pennies as JJHFL said because I have not used acetone to clean coins in the past. Any recommendations on brands or anything like that? All tips are welcomed.

amida17: thanks for the info, it will come in handy.
PennyPiggy: I wouldn't send it to NCS or something like that because it's not a coin worth hundreds of dollars. At most, if the cleaning turns out successful, it will be a $15 - $20 coin in my estimation so it's not worth the hassle. If it were a 1909-S VDB or something of that sort then I would consider NCS, but not with this coin. Thanks for the suggestion though! :)

erns,
Yeah, I just tried to offer something up as an option to consider. The fees would probably be 10 for the eval, 15 conservation, and I think 17 for the economy option for grading ugh plus shipping!! Ugh ugh.
I just hope it works out for you Good luck and nice find. I would like to be in your situation!

It is not difficult. 2 Glass containers. Pure acetone (from Home Depot or Lowes). Penny.
Place penny in jar. Pour acetone in. Cover. Let sit for 24 hours. Using tongs, pick the penny up, swish it around to knock off loose gunk. Set penny aside. Place penny in second glass container. Por acetone in. Cover. Place first container with old gun filled acetone outside to evaporate.
Once the acetone has evaporated, you will need to clean out the container to remove gunk that was left behind. Continue 24 hour rotations until the gunk is gone.
So what if there is a variation in color under the gunk? That is a non point IMO. You would leave that crud on there for the sake of difference in tone? Really?
This is a very simple process that will NOT do anything to the coin. Search the word acetone in the forums and you will get plenty of reading material.

I would soak in acetone as well. If the gunk didnt dissove I would use the very end of a qtip or a rose thorn to try and remove some of it. Repeat as necca sary until I achecvied my goal. Acetone wont harm coins and neither will the tools I mentioned when used properly. Good vibes and great find. Please post after photos.

Any recommendations on brands or anything like that? All tips are welcomed. I got mine from Home Depot. Just make sure it's acetone and not some other chemical or odd mix of chemicals with acetone and something else in it. And just to get a feel for it, I would try it out on a regular modern coin to get a feel for how it works before you use it for that 13-S. |

I have conserved many coins that had a very similar, organic residue. Once you remove that, there will be exposed metal and an obvious, tell-tail sign that it has been worked on. However, you have to decide between a residue-free coin and one that looks like it does now. In cases like this, I personally prefer to remove the residue.
ALWAYS follow the POLARITY LADDER when undertaking ANY conservation project. People here are far too quick to recommend jumping straight to acetone. Without exactly understanding the composition of the residue (which most people don't), you ALWAYS want to start with distilled or deionized water. It is by far the least harmful solvent for coins.
Soak the coin for 24 hours in water. At the end of the 24 hours, keep the coin under fluid and gently work the residue with a toothpick. If it's not budging, then water will not be the best solvent. At this point, I personally would go directly to xylene. By the look of the residue, these are typically long-chain organic (gummy) materials. Soak for 24 hours in xylene (sealed glass container), then, again, work the residue with a toothpick while under fluid.
If the gentle process outlined above fails, I would take this coin to the sink. Hold it under super hot running water and work the residue off with your fingers (only). You'd be surprize how well this actually works with low-dollar coins.

I just looked up the value for this coin and it's around $9 so I would be kinda careful with it. I don't think a "dip" in acetone will do,it needs a soak. I don't know enough about acetone to say weather or not to use it or how long a soak would be safe. Read up on acetone use and keep us updated. John1  |

Once the acetone has evaporated, you will need to clean out the container to remove gunk that was left behind. That will be a whole lot easier to do it you DON'T let the acetone evaporate. If you let it evaporate it will just deposit the gunk on the walls and bottom of the container and the only way to really get it off will be to redissolve it with acetone. So just dump the soaking solution on the concrete, and rinse the container a couple of times with fresh acetone dumping that on the concrete as well. The acetone will evaporate from the concrete just as easily as it will from the container but all the gunk is now on or in the concrete and not in the jar. |

wouldn't it be best to send off to ncs and let them see what they can do to conserve it NCS would not conserve this coin. If they think the outcome will be undesirable, they will reject it and send it back. Not to mention the costs would exceed the value of the coin. Definately the case with this coin. |
