The difference is the time at which the expansion takes place (either
read-time or eval-time).
E.g. try

    (defun foo () (interactive) (message "%s" #$))
    (defun foo () (interactive) (message "%s" load-file-name))

if you load a file containing one of the above lines and then you do
M-x foo RET you should see that the first returns the file name
(i.e. the value of load-file-name at the time the file was read) whereas
the other returns nil (the value of load-file-name at the time you
called `foo').
