He's likely going to need the money within a year.
I don't care how much you may think silver is a "store of value" over the long haul, it isn't a very good one for the short term. Brandon was spot on.
Any reasonably populated area has a few cash4gold stores by now, or some other such similar business. I can convert my precious metals into liquid cash just as easily as I can empty out my bank account. (And I can sell all my stocks and wire the cash to my bank account with the click of a mouse)
And while precious metals may swing up and down from month to month, I can tell you that within a year, they will be worth more than they are today. The general trend is up.
People on this site seem to understand macro economic trends fairly well, but have terrible financial intelligence. When you're 18 years old, and you have some extra cash to invest, you buy ultra risky assets for the greatest possible return. When you're 62 years old, you buy ultra safe assets with virtually no return.
Its a very, very simple principle based on the fact that a middle class 18 year old is going to make $1000 thousands of times (and with high inflation maybe hundreds of thousands or millions of times) over their working life.
You don't need to worry about saving for retirement. That's utterly ridiculous.
Read Rich Dad, Poor Dad. Start doing some research on some ETFs and stocks you may want to buy. I recommend looking at precious metal mining companies, agricultural companies, and oil companies. If you accept the macro economics preached on this forum, then these are all great buys.
And, again, even if you lost 100% of that investment--which you won't investing in those sectors--that's $1000 of financial education that will probably serve you better than your $100,000 college education.
