I just added three of the quarter-follis denomination issued only at Sisica and for only a short while around AD 306. They have the usual follis GENIO POPVLI ROMANI type but in miniature (only 19 mm instead of 27 mm). http://augustuscoins.com/Tetrarchy.html Two are illustrated below. I also added something new. I put about 50 low-value coins on a "junk box" page. If you order anything else from my pages, you are eligible to pick from those unattributed coins at low junk box prices. http://augustuscoins.com/junkbox.html
