how much is 10,000 roman denari in Canadian dollars?

just cureous, and i mean what it would be work with inflation, etc.. like what is 10,000 denari 2000 years ago equal to in current Canadian currency, or american currency, thanks
edit : no i mean what did 10,000 mean to them, for example how much denari did a beer cost in rome for example.. is 10,000 denari to them like 10,000 dollars is to us now?
