I found this while I was searching through about 200 Sc 741. I found two of them with the "BAD" cancel on two stamps in the exact style. It appears they may have both been on the same cover. The 2nd stamp has a lighter impression.
I did not find the "BAD" cancel in the Skinner 1845-69 Book or the Herman Herst 19th century fancy cancel book.
The attached photo is accurate as how I see the cancel.
