Thanks for the quick ping back
Peter. Much appreciated.
I do have the Harl book and several others on the topic. The economics and use of currency of various eras is a long time interest so try to add books to the
library as I run across them. One of the most interesting/fun of this ilk is
The Big Problem of Small Change, addressing an issue few collectors think about. What fun!
The description of the reforms of
Aurelian is what caught my attention and why I was interested in sources, since this is only one intrepretation and the issue remains controversial.
Still, this is a very nice summary despite the obvious and necessary caveats.
Thanks again.
