Most old US silver coins were made of 90% silver and 10% copper (*) so at worst you'll get their current metal value from a scrap dealer, minus their profit of course. That varies depending on the current price of silver so you'll have to check a site that monitors prices.
Of course, most of those "we buy old coins" places will take a heavy cut for their profit so you might be lucky to get 1/2 to 2/3 of their raw metal value. Also, depending on the coins' dates and conditions they might be worth a LOT more to a collector so selling them for scrap would be like selling a painting for its canvas. If any of the coins are earlier than the 1950s you should check out their collector values before selling.
No, banks do not usually buy silver coins. However, you can always go to a silver and gold dealer and exchange your precious metals for hard cash there.
Each denomination of US silver coins has different amounts of silver, so it's not possible to answer this question. Be more specific and post new question with the dates of the coins.

Most coin shops or jewelry stores will buy silver coins at around spot price. Ebay and Craigslist are other places to sell your coins.
It depends how much you have and what type of coins you have. Are they collector coins (as in, high grades, key dates, rare coins) or are they junk silver coins (as in, worn silver quarters from the 40s, silver dimes from the 50s, etc.). If they are collector coins, it is better to sell to a reputable dealer. If they are junk silver coins craigslist and eBay are your friends, but dealers and jewelery stores will usually buy them too. Don't go to places like "Cash 4 Gold" or other "Hotel Lobby" sellers. They will often times take 50% or more off the true value of your coins.
Always buy coins, well known and collected coins such as the American Silver Eagle or the Canadian Maple leaf. They sell for a small premium above spot silver price, but are much easier to liquidate because their silver content is known. The Silver Eagle has numismatic value too, some coins that were sold as bullion are now worth thousands.
