I wouldn't; it's beautiful as is.
But if it's Tyche, Secvritas or Salus seating on the reverse, I couldn't tell you.

Just a little bit, i need to see the details..🙄 Should I leave it in destilled water?
Do you have any honey locust trees where you live? The ones with big thorns? I saw a guy on YouTube using them to scrape crud from Roman coins without damaging bronze patina. Check YouTube for “coin cleaning”.

Wouldn't a toothpick do the same thing? Or are they too hard or something?

A fantastic find - congrats !
If you do decide to clean it in any way be very careful.
It's very easy to loose detail /damage old bronze coins if you clean them the wrong way.
Keep in mind - this process can not be undone !
Good Luck !

One part 30% Ammonia in two parts destilled water. Cover the bowl you put the coin in or the ammonia will dissapear in the air.
Watch the coin every 5 minutes, take it every time out and clean it carefuly with a very soft tooth brush and dont use force!
So you got control if it is made out of bad silver and start showing a damaged surface.
Repeate it until all hornsilver is gone. When finished, dip ot one more time in and than let it dry.
Don´t wash it if you want a natural cabinet patina should grow back again after some weeks or month.
Most roman Denarius exept Antoninians was made out of good silver and for 99% you don´t have to fear the chemical cleaning could damge it. The use of Ammonia also nutralize Chlorides which can damage coins.
You can spot if there was chloride in it if the solution turns into blue.
Here are some examples of my chemical cleanigs
