[ 479 ] 
In the Pembroke colledion is a gold coin, or ra- 
ther medal, of Lyfimachus, weighing 540 grains. 
Mr. Duane hath another of them, which wants but 24 
grains of the fame weight. This piece fliould 
weigh 8 Drachms, and is of great importance on 
that account, as large weights and meafures are 
more to be depended on, in inquiries of this kind, 
than fmailer. According to this coin the Philippic 
fhould weigh 135 grains, and the double Philippic 
270 : but none have yet been found to come up to 
thefe weights. Some few filver Tetradrachms ex- 
ceed 270 grains, but they are very uncommon, and 
far the greateft number of fuch as feem mod: per- 
fedt, full diort of 266. Neither is the ancient filver 
fo corredldy fized, as to (land in competition with the 
gold of Philip and Alexander. Therefore, either the 
mint-weights of Lyfimachus were heavier than the 
Philippic flandard, or his money was lefs carefully 
fized: or, laftly, this piece, being intended rather for 
a medal than a coin, was purpofely over fized.. 
The filver coins of Philip and Alexander confirm, 
what the lexicographers tell us, that the golden Stater 
of Philip, weighed two Drachms. 
In the Britifli Mu feu m is a Drachm of Philip, 
weighing grains, and another of Alexander of. 
66], both perfedt. In the Pembroke colledlion is 
one of Alexander, which weighs 67 grains. Thefe* 
give a didrachm of 1 34], 1334, and 134 grains.
