If those are 45LC then I been doin’ somethin’ wrong, very wrong!
Balloon head? I'll probably never come across any old brass, but what is this?Not really. It's a straight wall cartridge. The real issue is some of the old 45LC brass is balloon head and shouldn't be used in a modern gun. Only thing I can think of is if there are multiples of the normal dies found in a 3 die set

@KnotRight curious what dies you have there as well. Sizer is carbide? Like the others said, straight wall nothing special.
If you section modern brass, the "head", where the primer is housed is solid all the way around the primer and then some. The old balloon head cases were manufactured a different way with the case head being much thinner and the primer pocket just an extrusion into the inside of the case. Given two cases of 45LC, one balloon head and one modern, the older one has a significantly higher powder capacity but that's at the expense of case strength. So long you stick with modern brass, you'll be fine, but when shooting a cartridge whose lineage extends back to that period, keep it in mind. Other rounds from the black powder days were made the same way.
These are the 45 LC dies that I got.

From the top down Lyman TC 45 Colt FL, Lyman Exp Die M-1, RCBS Seater #3, RCBS Taper Crimp and a Lee 45-Colt 84 die.
Also please note the 3 shell holders. Thr top one is different in that it has a long tube and will not fit into an RCBS or the like press. The 3rd one is smaller than the regular shell holder. And I have no idea what the piece is above the seater arm.
Should I go and buy a new set of dies?
