Well, hold your silver horses! We've got a classic case of mistaken identity on our hands. The U.S. Mint actually took a break from making silver dollar coins in 1957, so a coin from that year doesn't exist. What you're almost certainly thinking of is the 1957 one-dollar Silver Certificate, which is a piece of paper money, not a metal coin.
These snazzy-looking bills with blue seals were the last of their kind and promised that you could, in theory, swap them for a dollar's worth of actual silver. Those days are long gone, but the bills themselves have become collectibles.
Based on the market, the value isn't exactly a king's ransom, but it's certainly more than a buck. For a 1957 Silver Certificate in "Fine" condition—meaning it's been circulated and has a few wrinkles to show for it—you're looking at a value of around $13.75. If you have one in crisp, uncirculated condition that looks like it just came off the printing press, it will naturally be worth more. So, while you can't trade it for silver anymore, you can definitely trade it for more than its face value.
