RIC VI 17 (London); CT (Cloke & Toone) 2.01.007. Cloke & Toone combine RIC 6b and 17 into one catalogue number due to the presence of continuous variation in bust size; there are not really two distinct bust types as RIC would have it.
From the James Pickering Romano-Britannic Collection (please see lot 122 for details), acquired from Forvm Ancient Coins.
This is a clear example of the the "refined" style of C&T 2.01, and of a larger bust that catalogues in RIC as No. 17.
