Thank you for the replies. Straying out of the bronze coins into silver is pretty new to me, so maybe I'm being over cautious, but I feel better getting the opinions of those more knowledgeable.
@Palouche Yes Paul, it does indeed look like a very close match, and I'm sure it must be the one.
@january1may A thousand times better than my definitely non-expert eyes!
@sel_69l The reverses don't match exactly, there are a few small differences, so it doesn't look like a matched die pair. On closer examination with a glass, the cracks do appear to have sharp edges.

I had mulled over whether the last letter in the exergue was a "D" or a "B", but I do see now that it would be a "B".
Thanks again,
Jim
