Great assortment @rg3 !! The Athenian tetradrachm is beautiful, but my personal favourites and the denarii of Augustus and Antony!
My favorites are your Augustus and a tossup between the Gela/signed Syracuse. All are beautiful examples - congratulations!
Those are all really nice coins! My favorite are the Proto-Tortoise, Proto-Tortoise and that Athenian Owl! Congrats!
Lots of fans of the Owl, for good reason. So let me praise the Augustus denarius. An interesting coin, as all are.
