Roman denarius? - This is probably fake right? [opgelost]

I got this a few years back on Ebay, think it was about 15-20 pounds and I've never really added it to my collection because afterwards I kind of thought it was unlikely to be genuine.
Well anyway, can someone please give me their thoughts.

Weight 2.4gr
Diameter 17mm
depth 1mm

Antoninus Pius Denarius. ANTONINVS AVG PIVS PP TR P XXIIII, laureate head right / FELIC SAEC COS IIII, Felicitas standing left, holding caduceus and leaning on short column. RSC 361.

I see no reason to doubt its authenticity, 15-20 pounds is about the correct price for such a coin. Add it to your collection, it's real.

Hello, its genuine, no doubts
congrats!

Thanks gentlemen your replies are appreciated.
