Unknown Roman?

Hussulo

Can anyone identify this coin for me? It is a little worn but the details are better than the scan in hand. I have had it for years but don't know what it is.
It is a large coin bronze coin roughly the size of a Half Dollar. It depicts a bearded man on the obverse and a galleon/ship with sailors on it on the reverse. It has an S on the left of the ship plus a C on the right of the ship.
Thanks in advance.

Without clearer pictures, I am tempted to say that this may be IMP C M CASS LAT POSTUMUS . . .
Postumus reigned from 259 to 268.

I am unfamiliar with the reverse design, at least from what I can see. Could be Seaby 3042; a sestertius.

CIVITAS

harasha is right about the ruler and time period. It's a Double Sestertius though. Radiate crowns on Roman rulers = double.

Not especially rare, but looks to be a decent piece and they're popular with collectors.

Is it the same/similar coin?

It is difficult to say without a better shot of your reverse. Nevertheless, you coin appears to be nicer.
