Other people have pointed it out, but just to reiterate:
This image is 1) A Ferrotype (or "tintype"). Process not patented until 1853, and 1856 in the US. By the time this image could have technologically been taken, there are already existing photos of a more mature Lincoln. 2) The clothing dates from the late 19th century. Fashion does not, and never did remain in a bubble, and a no one goes around sporting 50 year into the future fashions.
Any appraiser or historian who specializes in photography or fashion would instantly know that this image could not conceivably be from earlier than the 1870s at EARLIEST.
