@alpha2814, you could start by giving it a bath in acetone.

If the first two pics are accurate from a color standpoint, then perhaps there is some sort of environmental damage here. I would try Verdi-Care if you want to pursue it, but it's not a valuable coin however it turns out.  Edited by Coinfrog

The first two are color-accurate -- the close-ups are from my microscope and its built-in lighting. That was an attempt to show what detail remains.
I have acetone on-hand, I might try that. I'd be content if it "returns" to an all-green state -- the color is pretty cool, despite whatever happened to it.

The green patination would have been most attractive, if it had been an ancient Roman Sestertius and would have added to the value.!  A keeper. It is in rather nice condition anyway. Keep away from other coins, so as to avoid the spreading of bronze disease. |

I'm thinking the coin was painted a long time ago . I'm sure it's not environmental damage . Go with the Acetone soak maybe 2 or 3 days .  |

If it were mine, it would get a long acetone bath (days). That's the definite first step. What comes out after that will determine any additional steps. It has great detail and it's worth a shot. Keep us posted!  In Memory of Crazyb0 12-26-1951 to 7-27-2020

It's soaking now. I've had this for about 40 years, one of my favorites from my childhood collection. Got my fingers crossed...
Should I give it a gentle brush with a Q-tip along the way?

I would give it a couple days, maybe lightly swirling the acetone to stir things up a bit several times, and then change it over to new acetone. After a day or two more, it may be necessary to use a manual method of removal because even though the acetone may soften the gunk, it may not come off entirely and/or particles in the liquid will settle back onto the coin before you take it out. A cotton q-tip (with paper stick, not plastic) has been my go-to after acetone baths. I dip it in acetone and move it along the surface. The most suttle way that has been effective for me is to roll it across the surface so there is no real abrasive horizontal movement. That's what I do.  In Memory of Crazyb0 12-26-1951 to 7-27-2020

I think it is just the green you get with old oxidized bronze. If I remember correctly it actually protects the metal. I would verdicare it and put it in a nice 2x2. XF/au detail. I have used verdicare on coins like this. Sometimes it turns them dark bronze other times, not so much.

@Alpha If you don't have any Verdi-Care yet, definitely get some. It can do great things to certain coins in need. It may seem a little pricey but, that little bottle goes a long way. Still, as you've done, acetone should be the first step to remove contaminants. Then, maybe some light manual removal options. The Verdi-Care I ordered from ebay came with several hardness levels of wood picks and a towel to boot! Then, Verdi-Care per the instructions.  In Memory of Crazyb0 12-26-1951 to 7-27-2020

Thank you all, I'll shop for Verdi-Care in the morning, when my brain is a bit clearer. In the meantime, the acetone soak will do what it can.

In my opinion this coin spent some time in the ground, and
is most likely a metal detecting find.
I agree with the acetone and verdi-care treatment.

Verdi-Care on the way, and no, I did not know a CCF member made it. That would explain why Amazon doesn't have it, but at least I got almost $3 in ebay Bucks (8% promotion, and I splurged for the cloth and thongs). I hadn't considered "in the ground", I guess because the green is so vivid and consistent, except where it's not. That makes me feel better about the soak, fearing that paint (or possibly a bad plate) would come off in a less appealing way. |
