You won't get silver coins from a bank. They are worth more than face value, and no one is going to deposit them in a bank unless they are ignorant. Collectors and speculators have them. You can buy them from a coin dealer, but it may cost you $40 for a silver dollar.
I had about 10 silver dollars back a few years ago. Sold em. Made nearly 200 bucks. I think the last coins that were made that weren't just plated, were silver dollars. I don't think any country anywhere makes pure metal coins any longer, aside from African Krugerands and those will cost you a leg and both nuts. BUT, in times like these, gold and silver are excellent investments.
You cannot buy silver coins from a bank and as for keeping it, the bank is the last place you would want to put your silver coins. There are precious metals dealers and collectors that have supplies of silver coins where you can buy at a low rice. Even better is a place online where you can buy dealer price (lower price) silver coins and get exposed to collectors and investors who share your interest in precious metals.
