Improperly cleaned coin

2 posts in this topic

I am new to this so forgive me if this question has already been asked...I have submitted several coins that came back "imporperly cleaned".  Is there another step I can take with these coins or are they forever marked this way?

 

thank you in advance

Thank you for your question. Unfortunately our NCS conservation service is not able to restore the coins once they have been deemed improperly cleaned. At some point during that coins lifespan there was some improper or harsh cleaning done to the coin that has damaged the surface.  NCS can remove harmful residues from the surface of the coin and stabilize its surface but cannot remove damaged from cleaning. I have copied the link to our details grading brochure below.
