Thanks for information but I have Martin's book who refer most varieties of this
Mint so I already know it.
what I think strange is the naked but on an as because naked
bust are only refered on
sestertius of year 3.
I made some
search on the web and I have find the
collection of a great collector who have 1 naked but on a
sestertius of year 2 but except the
asses of Arminius and the mine, I don't know any other and I didn't find any
dupondius with naked
bust. I think it's quite strange.
The size of the coin is also surprising for an as, in Martins book, the
asses have a size of 18-21.5mm (except the onlyone of year 4 with
gordian crowned by
victory which is 22.5mm and 5.63g), this one is 24mm it's even a little more than a
dupondius who have size of 19-23.5mm...
In my own
collection, the
asses are of 19, 20 (4 times) and 21mm,
dupondii are of 23 (10 times) and 24 mm (2 times)
the
weight are
Dupondius 7.89, 9.30, 8.09, 7.00, 7.20, 7.85, 6.67, 7.16, 7.70, 6.88, 6.61 and 7.60g so
average weight is about 7.50g
As 2.99, 4.82, 5.01, 3.88, 3.53 and 4.56 so
average weight is about 4.13g
the 2 wides as refered are
Asses of year 4 and the naked but I just bought have a
weight of 5.63 and 5.23g so
average weight is 5.43g so 1g more than
asses and 2g below
dupondiiIn Martin's book,
average weight of
asses is 3.58g and
average weight of
dupondius is 6.13g so these 2
asses are nearest of
dupondii...
So I think it's important to study them...
