Here is a piece I purchased as found. The before pictures are after soaking in DW and with a little vulpex soap. The after photos are after 3 separate 30 minute cleanings with hand
tools. after each cleaning the coin was re-soaked in distilled water for 1-3 days.
I think the coin turned out great and has wonderful details for a buried coin. I will take care of the last
bit of cleaning on the
obverse in the next week or so.
Before and after photos. The last picture was the seller picture
