Is the 911 Twenty Dollar Silver Certificate from National Collectors Mint Really worth anything?

No. This is the not the first time this company has tried to profit off the 9/11 tragedy. They were shut down by Eliot Spitzer the first time, and I understand there is an investigation underway over this latest effort. They claim they are selling it for "face value," but there is no "face value." It is not legal tender, and it is very likely a scam.

What is an 1883 o mint mark silver dollar worth?

  In circulated grades it ranges from $18 to $27. MS-60 (typical uncirculated) goes to $36 and the higher grade grades rise quite a bit to $435 in MS-66.  

Thanks for the feedback!

What is the 1942 silver dollar worth with no mint mark?

The last large-size silver dollars were struck in 1935. Please check your coin again and post a new question with its denomination and condition so it can be ID'ed. Thanks.
