I have added a few coins including a nice Class I anonymous follis, and a scarcer Class F follis, plus a couple of Licinius copies of the radiate "12 1/2" denomination. Also, a small AE Octopus from Syracuse. http://augustuscoins.com/index.html Books: I also have (not yet on my pages, but offered here) the large two-volume book by Estiot on coins of Aurelian and Florian, "Monnaies de l'Empire Romain, D' Aureline a Florien, 270-276", with 456 pages in French (most lists, tables, and coin IDs, easy to read), plus 100 page plates and 16 pages of color enlargements and many tables. This copy is excellent. None on Amazon. AddAll at $199 or $220 but shipped from Europe. Here, a very good copy at $180 including shipping in the US only. Massive: SNG France 6.1 "Italie, Étrurie - Calabre" Paris 2003. 141 page plates of excellent photographs (better than older SNGs). Nearly new/ [$79 shipping in the US included] I hope you find something of interest.
