RIC -; UKDFD 39525

Found by Mark Hildreth and Colin Popplewell near Stamford Bridge, Yorks in November 2012.

With kind permission of the UK Detector Finds Database, Nov. 2012.

The coin is only the second known antoninianus of Proculus, 
the first sold by Munzen und Medaillen in 1994 (also
here on wildwinds.com). 
The present coin is from the same obverse and reverse dies as the 
M&M example, but the reverse is better centred, with the entire 
legend on the flan. 
Both coins would appear to have a higher silver 
content than the official issues of Probus.
