C dot I dot P dot P, bust of Selene (?) right, with
crescent on head.

RPC 5405, listed under Uncertain Coins". 
Extremely rare, possibly only the second example known,
and with clearer legends than the RPC example.

The RPC plate coin is in the collection of "JSW" (a 
collector in Texas, USA) and adds: "The provenance of this 
unique coin is unknown. The size and the signature of 
aediles may point towards Parium (RPC 2253-2259); but the 
regular ethnic of Parium is CGIP not CIP[, which might 
indicate an African mint like Colonia Julia Pia Paterna,
where quattuviri signed an emission under Augustus (RPC 760).
