Removing the Dirt from an 1837 Half Dollar that was buried?

Question

Hi,

I found an 1837 Half Dollar that was buried. At first, I thought it was a large cent because of the color, but after years of being in the ground, this coin has a thick residue of dirt, etc. on it.

I am usually against cleaning coins, but in this case, I am looking to remove the dirt buildup, etc. Anyone know how to do this without harming the coin? I know scrubbing it in any way will damage it further.

Thanks a bunch

Answer 1

try getting ahold of the device jewellers use to clean jewelry. It's a cup with water and detergent that vibrates at a very high rate.

Answer 2

It really depends on how bad the dirt is sometimes a soft brush can remove some

Answer 3

soap and water, if you want to scrub it , use a toothbrush
