Cracking Open A Garage Sale Safe - Big Score?

I bought this safe at a garage sale for $10 with the possibility of untold riches inside! Will I score big or will it be a dud. This is a fireproof Hercules 1 hour safe made by Meilink in Toledo Ohio.
I've never cracked a safe before and I am not a locksmith, so we'll see how this goes!!
The safe hasn't been opened in a long time, the people I bought it from never saw the inside of the safe since they didn't have the combination.
