Bought this coin at a local fair and it has got a good description, though it's not on Numista and i don't have the books to reference it. I even tried my local shopto see they they had the books.
What i know is:-
Germany - Pfalz-Zweibrucken
Wolfgang (1532-1569)
Ar Pfennig, ND, Meissenheim Mint
W above adjacent shields of Zweibrucken, Wittelsbach & Wittelsbach (old)
MB24
Only image on Obverse .
Weight = 0.18g
Size=13.3mm
Is the description Accurate?

Thanks
