I have conferedate 100.00 bill made in Richmond Nov. 2. 1862with the noting confederate state and U.S. on it also the picture of slaves hoeing cotton. This is very interesting bill and I want to know the value of it and how can I sell it

Some are real, some are old counterfeit, some are new reproductions.
You will have to take it to a coin dealer to find out.
You can look on eBay to see what each type is selling for. A lot depends on condition too. There are actually a lot more of them around than people think, so most are worth in about the $30 range.
