This Siscia VLPP has an unusual shield decoration. There are perhaps 4-5 different shield designs (horseman, studded, vertical lines, plain (with or without shield boss) and assorted patterns (like this coin) are the main types) with a great variety of differences among each design; but this one is very different. It is also a rarer design...I have had only a few examples over the years and seen a few more. I really don't know what is depicted on the shield-- though I believe it is probably a floral design; but might be an astronomical element or perhaps just a geometric pattern. The crossbar of the helmet also has what looks like a lower case i.

I found a picture of an Irish shield (O'Donovan's shield) from around the 15th century with a similar pattern
I just saw some very similar examples of this shield design. Below is a Byzantine silver plate from A.D. 629-630 depicting the battle of David and Goliath.

and a Probus coin with a similar floral design
here's a lead amulet with the same design
here's a Crispus from Siscia with a floral design that I was the underbidder on.
