Those cracks should make it easy to determine if it cast
. A crack
is rough and sharp
inside. A cast
of a crack
cannot copy the internal detail. The coin does not look cast
in the photos.
Raised spots like these can be from die damage. Dents in the die produce raised spots on the coins.
The sort of bulge you have in the left field
does often indicate corrosion of base metal within. With those edge splits, if it is a fourree
, I would expect to see some bronze in the cracks. If you don't see any bronze in the cracks, it is probably an official coin. Perhaps the alloy
was not mixed well enough and there is an internal lump of bronze that has some corrosion. Or perhaps it was a dent in the die.
