Best Way To Get Rid Of The Green?

It is Justinian SB-160

This is what can happen when people think they are improving a coins appearance - not done by me.





I would much rather own a coin in a crusty condition than one that has been ruined.

Truly awful

I had my own "disaster" a few years back
I picked up a small lot of Postumus bronzes from a seller in France
Based on the evidence I presume he had dug them up as a detectorist out in the field. I really only wanted the largest that had a trireme reverse and the rest I sold off to recoup most of the expense.
The second largest Sestertius had a lovely glossy green patina but a few edge chips exposing BD beneath. The more I tried to rid the cancer the more the edges chipped until the entire rim was exposed.
And still the BD persisted !
Well stage 4 cancer calls for extreme measures if anything was to be saved at all. Using a 'secret' recipe I proceeded to bathe the coin for an extended period of time with slow but certain results. After about one week my bottle of 'secret' sauce was finished and I fetched another from the kitchen closet.
Unwittingly I opened a bottle that was double the strength of the one previously used !
I changed the bath water and set the coin back on the shelf.
Around two days later I went to check on it.



The glossy green patina had ALL been stripped away

A hard lesson learned
Fortunately for me the patient had already been diagnosed as probably terminal

Thanks, Seeker! I'll mix up some of that. One more arrow in the quiver.

Renaissance Wax is a protective wax put on when all cleaning is complete, like waxing your car. Used by the British Museum on coins and other antiques. Looks good! Available at ebay.

I considered that also, but I believe the part of the legend is off flan and the bust looks now like Justinian than Justin.
