I haven't seen this fake before so I figured that I would post it, though it isn't particularly dangerous. Note that the mintmark looks like PTRS, which is nonsense. It also has an unrecorded reverse and is much larger than an authentic coin from this period would be--- 31mm 21gm
I have added the seller to the fake list. He is selling other junk also, like a Gordian II.
