1923 $1 US Silver Certificates are identified by their blue printing and the words SILVER CERTIFICATE at the top of the bill.
Auction values as of 11/2009 are $6.-$35. for circulated specimens and $60-$125 for uncirculated ones if they carry the signatures Spellman and White. Other signatures are worth somewhat more.
Note that a bill's serial number rarely affects its value so you don't need to copy it into a question.
In God We TrustThat motto wasn't added to $1 bills until 1957 so it won't appear on older bills.
The Bureau of Engraving and Printing of the united States, never released a $100,000,000 bill. What you have is a novelty item that sells for a few dollars.
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
Silver certificates were never formally withdrawn so you could still spend one, but you can't exchange them for silver anymore.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.
It is really impossible to say without knowing the condition of your bill. Condition is everything and can mean the difference between a $20 bill and a $200.

How much is a 1957a silver certificate worth?
I assume you mean a silver certificate, not a dollar coin. Values range from $6 if worn, up to about $35 in near-new condition.
You shouldn't "cash in" a collectible bill. To cash in a bill means to take it to a bank where you'll only get face value (i.e. $1) for it. As you can see from the Related Question linked below, a 1923 $1 silver certificate would be worth much more to a collector or at auction.

The U.S. hasn't printed silver certificates since the 1960s, and there was never a $2 silver certificate.
It's a U.S. Note rather than a silver certificate. It's worth face value if circulated, $3 if uncirculated.
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.
Please look at the bill more carefully. It's a Federal Reserve Note, not a silver certificate.
