Unknown Roman Republic Denarius?

[Brunus]

Hello folks,
I've recently purchased this denarius but unfortunately the seller has no ID on the coin so i've looked it up & i think it might be from!!

D. Silanus L  Rome, 91 BC.

Obverse; Helmeted head of Roma right, F behind.

Reverse; Victory driving fast biga right;

weight; 3,25 gram
AR Denarius.

I would need to be sure that someone out there would know this type of denarius.
Thank you,
Sincerly,
Brunus
