Should I invest in Silver Eagles?

I'm 19 years old and work at a Sonic Drive-In. I start college in August, so no jokes please. I make around 350 dollars every 2 weeks (I know thats garbage). I'm very good at saving money, I have quite a bit put away. So if I bought 7 ounces of silver a month would that be a good idea? The value of gold and silver keeps going up and silver is available at 35$ an ounce. When the dollar crashes the value of both are expected to skyrocket. I know the old cliche you have to have money to make money, but I see an opportunity. Would it be worth it for someone in my situation?
