Nice sestertius : AE 66 mm, 176.38 g. Well... that's way too large and too heavy , it's probably a modern fake ... The Monnaie de Paris (Paris Mint) minted giant bronze reproductions of ancient and medieval coins in the 1970s and the 1980s. This one was made in 1973. Nice, isn't it?...
Here is another fake of the same coin. This one is a Paduan but a bit older than yours @GinoLR NERO 54-68 AD. Æ Sestertius Paduan? Rome mint, original struck 64 AD. Decursio series. Obv. Laureate head right, globe at bottom. Rev. Nero on horseback right, holding spear; behind him rides a soldier carrying a vexillum DECVRSIO RIC I 581 It would be nice if someone told me I was mistaken
