Can This 1864-L Be Improved/Conserved?

Its proprietary. Post a pic if approved for cleaning by me then send. You can then post Before/After pictures. Like NGC Conservation - there are limitations particularly of course with a copper alloy such as black spots, corrosion deep into the fields with copper other than green oxidation, etc.

You can then post here failure or success. Send me a PM. Will pay return postage - if the challenge is accepted. JPL

Although I got my COVID vaccination yesterday its the Winter/ Covid times / bored. Somebody post a picture. In the meantime any questions on Patrick's Canadian Blacksmith Tokens? <VVBG>.
