VisigothKing Pillar of the Community United States 4778 Posts	Posted 08/04/2014 4:07 pm I have a sestertius with a few cracks that range from small to downright tiny along the length of the edge, and a lot of them are filled with a green substance that seems to rub off. Its more of a shamrock or pigment green color (I thought describing it as "dark green" would have been too broad so I check shades of green on Wiki: http://en.wikipedia.org/wiki/Catego...des_of_green ), but it still rubs off, so I'm hoping it is simply minute traces of green gunk. I need a magnifying glass to see the green inside the cracks properly. And the tips on picks I use are too big to get into the cracks. It hasn't spread fortunately since I got it (a year ago), but I'd like the stuff gone just in case. What would be good ways to getting the stuff out? I'm guessing one effective way would be to dip/heat my coin up? I would consider that to be a last resort, since I'd rather not ruin its nice, brown color. I'll try later in the evening to get photos of the coin and its edge Edited by VisigothKing 08/05/2014 12:32 am Report this Post to the Staff

echizento Moderator United States 23731 Posts	Posted 08/04/2014 8:02 pm Try removing it with a soft bristle brush like a toothbrush. If that works the either rub in a little olive oil or wax to coat the coin. Report this Post to the Staff

Kind of hard to see but they're there in the photos, as the tiny green dots on the edge, in the small cracks: Quote: Try removing it with a soft bristle brush like a toothbrush.

I think I got some of it out of the not-so-deep cracks, but the bristles weren't able to get the green in the deeper cracks. Report this Post to the Staff
echizento Moderator United States 23731 Posts	Posted 08/05/2014 03:42 am Hard to tell but I don't think it's BD. Looks like you got most of what it is anyway. I think it will be OK, just check it from time to time and if it comes back than it's BD if not your all set. Report this Post to the Staff
