A lot depends on the colour (orange-brown or pink) and the condition.
For the orange brown, if the note is fully signed at bottom left and bottom right, book value is $85 for very good, $110 for fine, $165 for very fine, up to $425 for uncirculated. A remainder note (missing one or both signatures) will be worth about 40% less. If the note is pink, there will be one signature only (at lower right): $60 for very good, $85 for fine, $110 for very fine, up to $300 for uncirculated.
