flruck out of the Pound. He died in the reigh of 
Titus j and the mean Aureus of Greaves's table from 
Nero to that Prince, inclufive, is under 1 1 2 grains. 
That of the Pembroke ColIe6tionfor the fame period 
amounts to 113; but Nero’s coins (contrary to 
Hardouin’s reading of Pliny’s text) appear to have 
been heavier than thofe of Vefpafian or Titus. 
Snellius, in his book De re numaria^ hath given the 
weights, of eleven Aurei, from Nero to Commodus, 
which he fays were all as perfeft as when they came 
from the mint. The lighteft weighed 149 Dutch 
grains, the heaviefl 153; which anfwer to iio| and 
113I Troy. The mean taken from all the eleven, 
is almoft 1 12 Troy grains. 
Bouterouefound the Aureus from Nero toSeptimius 
Severus, to weigh from 133 Paris grains to 138; 
that is, from 109-^ to 1 13I Troy. The mean of 
thefe two weights is 1 1 grains. 
This ftandard continued beyond the reign of Sep- 
timius Severus ; and the Pembroke coins from Nero 
to that time, give a mean Aureus of almoft 1 1 2 grains. 
But we cannot fuppofe all of them to be perfe<5f. 
Greaves’s tables make it 113* for the fame period; 
but four of his pieces of Hadrian and the Antonines 
weigh from 117I to 12 1 grains; which is an un- 
common weight for that age, and might poftibly pro- 
ceed from an alteration of the ftandard, which did 
not continue long. ^ Excluding thefe four, the reft, 
give a mean Aureus of 1 121 grains. 
Eifenfchmid weighed a great number of fuch as 
feemed perfeft to the naked eye, and found the beft 
of them to exceed 136 Paris grains, or 1114. Troy.
