Thanks for the replies guys, heres a better picture. The thing is really dirty - Is there any reliable way of cleaning it without 'cleaning' it? I hear Verdicare works well, but id be concerned with using it. Any knocks are probably from when all the coins were poured out of the tin. Theres a small dent on the neck, but it doesnt look like recent damage, I think it came like that: Couldnt spot any marks on the obverse: So, how should I remove the gunk, or should I leave that to the buyer? Is it worth removing before posting for sale? What grade am I looking at here?
