Will NCS Conserve a Continental Dollar?

2 posts in this topic

Now that NGC is grading colonial coins - including Continental Dollars - I would like to ask: Will NGC do conservation work on an uncirculated Continental Dollar that has dark toning spots? A Continental Dollar is, of course, made of pewter which is mostly tin. I understand tin is a very reactive metal so the concern about permanently altering or damaging the coin is much greater than usual. Has NCS actually done conservation work on a Continental Dollar?

Yes, NCS would evaluate for conservation and potentially conserve a Continental Dollar. Niether the type nor the metallic content would prevent us from evaluating or conserving the piece.


We do work on types that NGC would not certify such as Ancients or certian types of medals and tokens as well as any type of numismatic item NGC would certify. Naturally, when submitting a type that is not eligible for NGC certification we would not be able to have the piece encapsulated after the conservation.


We also do work on metals that are not standard in U.S. coinage but are found in colonials, world coins, tokens, and metals such as tin or zinc. As with any coin in for conservation, if the work would cause damage to the piece, we would elect to not conserve the item. Finally, we have worked on continental dollars in the past.


Chris, NCS
