Philip I AR antoninianus, undated (AD 244). 3.6 g.

IMP M IVL PHILIPPVS AVG, radiate, draped and cuirassed bust right.
LAETITIA FVLMENNAT, Laetitia standing left, foot on prow, holding patera and rudder.

Note: The style of this coin and its unique reverse legend suggest that it is an ancient forgery from the eastern 
provinces. A loose translation would be "Joy the 
thunderbolt thrower". A second specimen, from the same dies 
but bronze has also been offered in auction.

From ettu-antiquities. on wildwind's server since 2006 but not properly added. Added in June 2010.
Although this is likely to be an ancient forgery, I am
adding it to the list to help anyone else who gets one.
Given the Ettu reference Ettu P1-111
This is the only known silver specimen. One other specimen, in bronze is known.
