This is an extremely rare variant with the title P P added to the long obv. legend used in 138 to early 139, before the title Pater Patriae was awarded. The first sestertius with this obv. legend appeared in the Garonne Hoard of 1965 and 1970, published in 1984, no. 3569, pl. LVIII. Additional sestertii were collected by Curtis Clay in 1996 and 2012. This specimen is the fourth known. Until now, all these sestertii have the Fides standing reverse type.
