That's what I was asking - how were these dies cut so closely? The process of it, in your opinion. Otherwise all of it is just a speculation, like the words of Fuchs about diemaker's mission.
In any case - my question is hypothetical, no need to answer it.
I recommend to all a great book by Denis R. Cooper - The Art and Craft of COINMAKING, A History of Minting Technology, By Spink and Son 1988. The guy used to be a Chief engineer at the Royal Mint. Many things will fall into place. Collector's talks and fantasies are often quite different from the actual die and coin making technology at the different times in history.
I wish Armen to sell the coin as it deserves and for seller and buyer to be happy.
