One city walls type is known for Macrinus (SNG Cop 543) and 
one for Quietus (SNG Cop 534) but without the figure of
 Serapis.

CNG sold one of these, Ray Wilk (this coin) has another, Dan 
Kinney has another, so there are probably several out there and 
it is strange that is not recorded anywhere.
