Watch List notes:

Mysia, Cyzicus. Nero. A.D. 54-68. AE 16 (16.4 mm, 4.19 g, 1 h). Struck A.D. 63-68. NEPΩN, bare head of Nero right; in left field, ΦΥ monogram / K-Y-Z-I, draped bust of empress right, ΦΥ monogram. RPC 2249; SNG BN -. aVF. Very Rare. Only three specimens cited by RPC, all in museum collections (one in Berlin, two in the BM [but both aquired subsequent to the publication of BMC Mysia]). Additionally, no further specimens are mentioned in the various RPC supplements.RPC 1 p. 383 describes the reverse empress. "The bust on the reverse was regarded by Hasluck (NC, 1906, p. 27, no. 4), von Fritze (Nomisma X 1917, p. 14) and vA Index as that of Agrippina II. Although certainty is not at the moment possible (because of the small size and relatively poor preservation of the coins), the portrait of Nero seems to be the "steps" portrait, introduced in 63. If so, the bust should be that of Poppaea (or possibly Statilia Messalina).
