I have 2 to 3 pre 1900 copper coins. Each one has a touch of 'build up' around a couple of the devices. Is it worth it to have the TPG conserve surfaces? Is there anyone who has had some conservation done and has input about it? Thanks! |

I assume you are asking worth it from a money standpoint, it really just depends what they are. There's plenty of pre 1900 that would without question be worth the PCGS/NGC fee and plenty that wouldn't be. No way to say without knowing what they are

 of the coins you wish to conserve. |

It depends what you mean by buildup, black greasy gunk, green oxidation, PVC residue. Then of course, cost effectiveness comparison, is a $10 coin worth $40 conservation fees?

I don't see any likely benefit from conserving these coins. Enjoy them as is!

I think they are nice as is. Don't disturb them.  Keep them in a controlled climate environment away from any PVC plastic and you should be golden. In Memory of Crazyb0 12-26-1951 to 7-27-2020

You are crazy if you do anything to these nice original coins pictured.

Don't clean or conserve them. They look like nice original examples. Almost all circulated copper coins with original surfaces will have some "build-up" around the devices.

They're only original once. I would advise against conservation or cleaning.

Try BadThad's list of solvents: http://goccf.com/t/39932Having a lot of old rolled pennies and other coins to search through, I had to find some way to combat this very problem. If the above list does not do it, I use a porcupine needle to remove the gunk from around the coin's devices. The PP needle (4.00 a sandwich bag full on ebay last I looked) is soft enough it does not scratch the metal (used on copper, silver, and gold). Looking for RPMs, I have scooped the gunk out of the inside of thousands of D and S mint marks with no problems. One needle can last a long time. Four dollars a bag is a lot cheaper then $40.00 per coin! How much squash could a Sasquatch squash if a Sasquatch would squash squash?
