A friend of mine is learning a very valuable lesson right now, good credit is often times better than cash. He comes from a very wealthy family and he lives off of a trust fund. He always has a lot of cash and always pays for everything in cash. He's never had a credit card or even a debit card. While his cash provides him enough to live off of without working (and will continue to do so for the rest of his life and maybe even his son's life) it comes out as cash sums when he needs it. He has no credit. Now he is in the market to purchase a house and no one will give him a decent loan. He can make a 20% down payment and make the monthly mortgage payments but since he has no credit at all, the lenders are sticking it to him on the interest rate. He just got approved for his first credit card (he's in his early 30's) and made his first online purchase (it is 2015!?!). So his options are don't get the house he wants, get raked over the coals with an outrageous interest rate or go into title with his girlfriend/baby's mama who has a good stable job and excellent credit. He told me the other day how he regrets never establishing good credit when he was young. He always thought cash would be good enough and it isn't.
So what does this have to do with the OP? I'd say pay off your loan with regular monthly payments + a few % extra on top. This will pay down your loan, establish regular payments/credit worthiness and you won't have to spend all the money you have in one blow. Add to your silver and gold stack as you go. You'll be setting yourself up as a young man to have good solid credit when you need to buy a car or a house, it will teach you monetary responsibility (sounds like you are way ahead of most guys your age) and it leaves you with some cash in hand for silver and dates with the ladys.
If you really believe in a huge financial crisis then who cares about loans and such? Just default on them since it won't matter as we'll all be paying for canned beans, clean water and ammo with fractional silver coins as we try to run from zombies and mutants. As SilverDJ said, "That's a prepper fantasy." Sales of prepper supplies and literature is big money now. It sells a lifestyle based on fear. A lot of the stuff in the magazines are a pretty good idea; extra food and water in case of a snow storm or power outage, medical supplies and the knowledge to use them, transportation, etc. Unless you live in a very unstable or war torn country (some places in Africa, South America, Eastern Europe, etc.) I wouldn't bet the farm on seeing hyperinflation or mobs of murders trying to steal your stack. I'd pay down your debt, build credit and build stack.
I will also agree with everyone about getting silver shot. I don't think anyone would trust it. what is the purity? did someone mix some stainless steel or lead in with the silver? I would want at least a round or bar with weight and purity stamped on it and unless it was a large bar ,personally, I'd rather have minted coins.
