cleaned/not cleaned
Posted: Sun Sep 29, 2019 5:58 pm
Hello all,
This is a rookie question likely but I'll ask anyway. I am gathering tricks/advice for telling whether a silver coin has been cleaned or not. You know how when you tilt a coin from side to side there's a sort of shimmer effect that appears to rotate around the coin edge? It seems to me that this is a sign that the coin has *not* been cleaned. Something about the surface at a microscopic level after it's been struck - this gets disrupted by the reducing agents that clean off the toning maybe?
Anyway, I'm just wondering whether this is legit?
