Hey everyone. I came across this last night and couldn't quite figure out what could have caused this toning. Dipped in something perhaps? Sat in a car cup holder and then washed? Maybe it came from the mint that way? I don't know. Looking for some other opinions on to what could cause this. And if it is indeed minted this way does it add any significant value? The pics sort of dull the toning down, in hand it's much more dramatic. Anyhow, I look forward for your replies.
I would say that is definitely AT, probably been sitting at the bottom of a soda can for 6 months in a guy's construction work truck...
I was leaning the same way, environmental damage, although something may have eaten away at it, it really turned out beautiful lol. I'll throw it in an airtite and put it with my oddities. Thanks all.
