Faustina II AR Denarius of an Aureus type. 

Obv: FAVSTINAE AVG PII AVG FIL, draped bust left 
Rev: IVNO, Juno seated left (with child on knee), holding 
sceptre, before her a small figure standing right holding 
corn ears, SC in exergue. 

The photograph does not show well that this coin is made of silver. 
The aureus version, RIC III 504 has bust right. The coin is 
made of good silver, is not a fourrée and does not appear 
to be a fake.
It is an odd coin, as "SC" was normally only used on 
AE (bronze, copper etc) coins.
