I'd like to thank Nerocoins (www.nerocoins.com/) and Noble Roman Coins (nobleromancoins.com/) for their help with this video. I also like to thank the Classical Numismatics channel here on RUclips for their excellent drawings. If you're interested in buying a T-shirt with one of those drawings (or images from dozens of other ancient coins), you can purchase them here: leob.creator-spring.com/
Finally, I'd like to thank Shawn Caza, author of "A Handbook of Late Roman Bronze Coin Types, 324-395," for his comments on my script.
