MYSIA, Pergamon(?). L. Sempronius Atratinus. Quaestor, circa 42-39 BC. AR Tetradrachm (25mm, 12.54 g, 1h). Cistophoric type. Serpent emerging from cista mystica with open lid; all within ivy wreath / Bow case between two serpents; monogram above, Q to left, thyrsos to right. Stumpf 3; SNG France 1767. Good VF.

See W. E. Metcalf, “A note on the later Republican cistophori,” SNR 88 (2009), pp. 205–209 for the assignment to L. Sempronius Atratinus. Cistophori with this monogram carry either a torch or thyrsos symbol. While it would seem logical to assign the former to Ephesos and the latter to Pergamon, obverse die links between the two issues suggest a single mint.
