RO-MA Commemorative struck 330 AD at Constantinople. Extremely rare, RIC VIII Constantinople 104 "R4" (2-3 known to RIC). 15 mm. 1.34 grams. This and its companion piece, CONSTANTINOPOLIS with a similar reverse are the rarest of the commemoratives of the founding of Constantinople. Very seldom offered, only a few per decade, and I have not seen the companion piece offered in many years. [$225 + $6 shipping in the US] For more coins from this time period, see http://augustusmath.hypermart.net/coinlist.html For one of the finest, most sensitive, portraits of Elagabalus, see the second coin on that page.
