I got it working with:
:nnoremap <silent> $ :<c-u>exec 'norm
'.((virtcol('$')-v:count)<0?0:(virtcol('$')-v:count)).'<bar>'<cr>

Since you're typing a number and then the mapping acts like
typing a colon, it will prepopulate the Ex command with the range
of lines as detailed at
:help N:
So if you type "4:" it will populate with
:.,.+3
The <c-u> is used to clear that out.
