Had to apply a patina, after removing the green it looked pretty bad. I think it turned out great tho.
I use a solution ive been experimenting with for some time, i would attribute most of the work to patience and a dremel tool paired with a stiff nylon brush attachment.
The removal of the hard green stuff was fantastic! Was there any corrosion under the green spots? It kind of looks like its been "silvered"? Is it just the picture?
I would not have given a second look at the coin you purchased. However, I would consider buying the coin after your treatment. It was an ugly duckling before which has turned into the swan.
This is really looking good on the surface of the cleaned coin -- including the remaining original dust in the crevices. Is there any possibility of posting one more photograph? This time a photograph of the coin in its pre-cleaned condition where we can get close up on the surface and that green gunk? I'm a new cleaner of coins so I am particularly interested in seeing what the pre-cleaned condition looked like before cleaning. Thanks @bsr045 and sorry if I am being a pain in the neck by asking for another photograph.
@bsr045 - I really appreciate it that you posted this photograph which I am going to study carefully. I want to see if I have any uncleaned coins in a similar condition. Thanks so much!
Great job!! On this case, we must to say much more a cleaning than a restoration. Personally, I don’t see real matters to clean an ancient coin. I’m could not be so radical on it as on the modern Numismatics. Virtually, I believe that almost all ancient coin, specially that with more than 20 centuries was in any moment cleaned. What’s make difference however is agressive cleaning, with removal of a stable and homogeneous patine, producing risks to create holes or to show corrosion under the crosts. This really not the case. About “restorations” with tooling, artificial patine or other stuffs, I run away of it.
