Need ID help on Follis?

[gwestcot]

This coin has a maximum diameter of 29 mm and weighs 12.9 grams. It has a large X over an M on the reverse and the obverse has almost completely been eaten away by BD. There are letters in the right and left field on the reverse and I can only make out a XDP(D=Delta) on the right field. I looked through Helvetica's byzantine spreadsheets but could not find a match.

Terrible condition, but a scarce coin: Justin II, SBCV 394 from Carthage.

Thank You for the help. Ya I bought the lot for some of the other coins and this was part of the coins I couldn't identify before purchase. I got a year 8 Maurice Tiberius follis with the U III mark in the right field(Theoupolis), a Justinian I follis(Theoupolis), and one of those Christ of Kings coins from Basil II and Constantine VII co reign. This just kind of came with the two lots of 4 coins that I purchased.
