I bought this coin in a lot on eBay. The pictures don't do the coin justice at all, but it is a very nice antoninianus of Tetricus I with a decent amount of the original silvering remaining. The coin is MUCH nicer in hand than the photos suggest. However, instead of the obverse being "IMP C TETRICVS P F AVG", it has IMP C TETRICVS.P.F.AVG", with dots between some of the letters. Is this a scarcer variety, or is it pretty typical?
