More information is needed. You need to know the bill's date, condition, and whether it has a small letter next to the date. Then check a site such as the one linked below for a range of values.
A $1 silver certificate series 1934 is currently worth about $20 in circulated condition, and about $40 in a nice, crisp uncirculated condition.DanUser:WorkingMan
A silver dollar from the year 1020 is worthless, as it is a counterfeit.
Silver certificates were never formally withdrawn so you could still spend one, but you can't exchange them for silver anymore. However depending on its date it may not make much sense to spend a silver certificate. Common ones (mostly 1957 $1 bills) are pretty much only worth a bit more than face value to collectors, but some older-date silver certificates can be worth much more.
$12.00
Depends on which series and what condition it is in. A series 1957 could range from $1.25 to $10. A series 1899 would be $100 or more, possibly much more if in high condition.

A silver certificate is paper currency. It is not a coin. No silver dollars were minted in 1943, and no silver certificates were printed with that date either.
