Hi there, I picked up this honestly just because liked the age of it, I have modern coins but would like to get the old stuff. I didn’t spend much at all on this, ($20) and I realize it’s not in great condition but I’m really intrigued. The slab doesn’t have much detail about it but I started looking online and maybe it’s Constans? In any case I tried to get some decent pictures, if anybody can offer insight I’d appreciate it. Just trying to learn a little.
