Re: Possible vertical misalignment
- I now have the coin. The weight is normal, so we know it's not a
tapered planchet error.
On balance, it looks more likely to be a vertical misalignment than a
grease strike. In favor of the VMAD hypothesis, I note the absence of
the design rim in the affected area and the fact that the unstruck area
has what appear to be typical tumbling marks. Also, this area is not
recessed relative to the nearby die-struck field.
On the negative side, the reeding is equally strong all around the
edge, and there is no finning of the rim at the pole opposite the
unstruck area. Also, die fill with a coarse texture can leave a
surface texture on the coin similar to tumbling marks.
Still, most grease strikes leave a well-struck design rim, and the
unstruck area is slightly recessed relative to the surrounding die
struck field. So I'm fairly confident it's a VMAD.
The clash marks are even more impressive up close.
