Richard,

These appear to be overpunched characters (a remnant of cardpunch
entry) and the characters directly translate into digits, with the
implication that the entire numeric field carries a negative sign.

If you isolate the field, Translate '}' to '0', J-R to 1-9
respectively, and multiply its numeric value by -1, you'll get the
correct effect. It's likely that someone has already had to do this,
but I haven't (in Python, anyway). Pretty trivial, though.
