Fascinating example of a topic in numismatics for which I have absolutely zero knowledge.
But I do indeed enjoy reading about you experts exchanging knowledge.

To me - the CCF discussion is interpreted like this:
Expert 1: I believe I have here a 1793 Vermont XQ-213 with "XRF-TAM" on the obverse indicative of die state 3 from the Machin mill
Expert 2: Close grasshopper - but that is actually XQ-209-B with the AR-32 reverse variety, Eagle standing left.
Great fun to learn from you experts - keep it up and maybe someday I'll understand a part of your specialized knowledge.
Take a look at my other hobby ...
