The layout of the back is essentially identical to modern $1 bills.
The front is similar but with some obvious differences, such as the words "Silver Certificate" and "In silver payable to the bearer on demand"; a blue seal and serial numbers; and the absence of a Federal Reserve seal.
Beyond that, an actual picture is much more instructive. While it's not Answers.com policy to say "use the internet", that's the best approach in this case. You can use any major search engine to look for "1957 1 dollar silver certificate images" or a similar phrase.

If you think about it for a few seconds, casting involves pouring molten metal into a mould, a process that wouldn't lend itself very well to something made from paper and ink. US paper money is printed, much like newspapers and books.There's more information the at question "What is the value of a 1957 US 1 dollar silver certificate?".
Your bill is called a silver certificate rather than a silver dollar bill. 1957 silver certificates are still quite common among collectors. If yours is circulated it might retail for at most $1.50 or $2.00 depending on condition. Also please note that serial numbers do not generally affect the value of a bill unless they are "special" in some way; e.g. a low number like 000000005 or a pattern such as 12345678
1957-B was the last series of silver certificates printed in the US. They were actually printed between 1963 and 1965; the "B" indicates they were the third issue in the series that started in 1957 (the first issue doesn't have a letter). Like all silver certificates, a 1957-B silver certificate represented $1 worth of silver metal on deposit with the US Treasury. The number of silver certificates was limited by the total amount of metal held by the government. Up till 1968 it was possible to redeem a silver certificate for silver metal, but that practice ended when silver was deregulated and its price floated on the open market. At that point silver certificates were treated just like any other $1 bill, and became simply a medium of exchange.
It doesn't look like anything because the last silver certificates were $1 bills dated 1957. You can find many pictures of other dates by looking online at sites such as the one linked below.
A date is needed. Please check your bill again and look for questions like "What is the value of a (date) B US 5 dollar silver certificate?" for more information.
If it's not crisp and looks pretty much like a new dollar, $2.00 to $3.00.
The serial number is just a counter and doesn't help ID a bill. It's a bit like trying to identify a car by what's on the odometer. Regardless, 1957 silver certificates are very common among collectors and retail for $1.25 to $1.75. A dealer will pay face value.
While it's not normal Answers.com policy to say "use the Internet", the best approach would be to simply use the image-search capability of any major search engine. Entering terms like "picture of 1957 US silver certificate" should bring up thousands of pictures.
