Very rare variety with pellet below MI, only one in Pella (Berlin), seven in CoinArchives (only three noting the pellet below MI).

It is interesting that no prior publication noted this variety, since the Berlin Museum piece was from the Prokesch von Osten collection, and was in the museum since 1875!
