evansuk2000 Posted July 25, 2014 Posted July 25, 2014 Hi all, recently posted about a collection of 3 coins I have bought, they arrived today, and the brass one has quite a large black spot on the outer rim that I'm worrying about, and also quite a deep grove...I'm hoping it isn't vertigris? Could someone tell me if it's anything to be concerned about, or I should still be happy?! Also what are the black marks on the front?Thanks!Will add pics in a moment. Quote

evansuk2000 Posted July 25, 2014 Author Posted July 25, 2014 If you click past the other pics (Stamps!) you will get to the other coin pics...3 in total. Quote
Peckris Posted July 25, 2014 Posted July 25, 2014 https://imageshack.com/i/ey576ef4jShould work?Please any feedback would be great.The link took me straight there (heaps better than the awful 'bucket ). It might be 'treated verdigris' which would look black, or else it's straightforward spotting (you often see black marks on brass threepences). As for the groove, you'll have to live with that I'm afraid. Still, the BoE dollar makes up for any shortfall in the other two Quote
evansuk2000 Posted July 25, 2014 Author Posted July 25, 2014 It's kind of course when I touch it, I'm hoping it's just spotting then? Will this take much value from the piece? Would you still keep it? I'm not too bothered by the groove, just the black spot (I think it's black...I'm quite colourblind)The dollar is lovely.And with my worry mind...any chance if it is the dreaded vertigris...it would spread to other coins such as the dollar!

However, if you're worried, keep it separately from other coins, preferably in a capsule or flip. I couldn't comment on the value as it's not my area at all, but you should expect some depreciation.

bagerap Posted July 25, 2014 Posted July 25, 2014 The black looks to be treated verdigris, so I tweaked your picture a bit: I think there is a residue of verd as shown, so take precautions. Good news is that it's still a £40 weight. More on a good day with a following wind. Quote
evansuk2000 Posted July 25, 2014 Author Posted July 25, 2014 Thanks both, and it shouldn't spread to other coins...although it has now been placed in isolation! But I had handled the 1804 dollar after etc! Quote
