Original Bill of Sale for slave 1855

I have an original bill of sale from my family papers....It was for the sale of an 11 year old boy....it is signed and dated....several years ago my mom laminated it....I also have a photocopy of writing that tells what the original is saying....any information would be helpful....The paper is yellowed from age and has some dark spots on it.....I can make out most of the words on the paper....thanks...Marti I haven't got a picture of it but can if you need it....I would like to be guided to where to take it or if it can be sold.
