Galba?

A few years ago, I had the oppertunity to buy a clockwork orange coffee table...and my wife shot me down...I will never forgive her. It would have looked sick in my man cave. Oh and great coin, and great handle.

Check the small spot on the reverse. Try poking at it with a wooden toothpick to see if any of the 'green stuff' crumbles away. If yes you need treat in the near future lest the whole coin slowly dissolve over the next decade into lump of powdery oxide.

I am not saying this to alarm you as it is not unusual for these problems to happen. I recently took out a favorite sestertius of mine which had some reddish iron oxide looking encrustations. Over the past 2 years since I had purchased it several people had recommended removal. The areas covered were small and represented only about 2-3% of the obverse. I thought they added some character and decided to put off the decision indefinitely. When I took it out recently to my horror there were bright green fuzzy spots mixed with the reddish areas ! Egad !
As my brother is more expert at the 'chemotherapy' than I it was sent out immediately for the cure. Some minor scaring is evident and the color has been changed. But it appears for now the 'cancer' is cured !

Google verdi-care and read through the information carefully. It is really good stuff, but you need to catch it early.
