Trying to Decide What to Do with This Sestertius of Trajan (green stuff)

I have been going through my collection of Roman bronzes lately looking for the dreaded B.D.

I hadn't paid much attention to my collection for the last couple of years, so an inspection was overdue. Fortunately, everything seems to be mostly fine. Just minor spots here and there.

The exception are some coins which were affected when I bought them.
This sestertius of Trajan is one of them. The green seems to be stable and hard, i.e. probably not B.D - and it has not gotten any worse for many years.
Acetone will not remove it.

However, I think it is unsightly, specially the obverse, and the coin could benefit if the green was at least subdued.

What would you do - leave as is, or gentle treat with Verdi-Care?

a little verdi-care wouldn't hurt i'd say, and will stop the process. looks like missouri green has moved in on it.

 

I'd give it a few soaks (and gentle dabs) in Verdicare.

 

If it's hard and crusty green, then I'd leave it alone (I love a bit of grunge on a coin => it keeps it honest)

Athena Numismatics makes you pay extra for that look!! (but in desert yellow)

 

I would do a verdicare treatment.
BTW, Nice coin!

 

Ditto. I think the green is not unsightly at all.

 

Dont clean it and dont treat it. It is fine as is.

 

I'd keep it as is too.

 

The coin looks great just as is. Has character.

 

I'd leave it too

 

I vote to leave it be. Looks nice to me.

 

I would not interfere with that coin at all. I think it looks great as is.

 

keep it so
out my collection:

 

VerdiCare won't strip the coin, it will just remove any loose verdigris and leave any that is hard and counts as patina. Nothing to lose, do the VerdiCare.

 

... yup, ya might as well remove all of that great ol' patina ...

=> everybody loves furniture that's been refinished!!

 

OK, the green stays (at least for now). You have convinced me.
Thank you all for your comments.

If I need to look at a 'cleaner' coin of the type (i.e no green), I can always look at this one (bit rough, but dark brown tone).

 

I'm with @Kentucky. Verdicare will not hurt the coin. It may not help, but if there's no actual BD, it won't hurt. My lone ancient bronze is covered in a hard, green patina and I'm not worried about it in the least.

 

Yeah, I really like my Chippendale with the red barn paint.
