Sear is not the best book for identifying late
Roman bronzes. You really want
RIC for a physical book, but when I
still collected these
types I found that the best resources are
WildWinds (Link points to the
Julian II page) and
RomanCoin.info.
RomanCoin.info has a spreadsheet that is linked(click on the "
VOT X" image in the reverses table) that you can open in Excel and filter by
reverse type and by ruler(
Julian II) to narrow down the possibilities. Then you need to try and figure out what the text on the coin is, the bottom of the
reverse especially as this is the
mintmark and is crucial for fully identifying it. Feel free to post back here of course if you have questions but you'll do yourself a favor if you can figure it out on your own.
