I am not sure whether this coin has bronze disease
or not, the photos is not that good
, but you can see the green spots on the lower left at the obverse
and at the top left at the reverse
. It also has a small green spot like this on the edge, and the colour of is sharper green than on the photo, which makes me think of it is BD. On the other hand the condition for this coin has not changed for the worse during the two years I have owned the coin. The big question is if I should, with the risk of maybe destroying the patina
, put it in Gringot #1 to be on the safe side
or if I should assume that everything is OK and leave it as it is.
In advance, thank you for any replies!
