Is it worth money to the owner? Can the owner trade it for ANYTHING?
@aygart any insight? After all we are following the instructions of your signature line.
Sure it's worth money to the owner, with a passport that allows him to travel across country, while without he would be bound to stay put, and would need to spend another x amount of dollars to replace the old passport.
And in regards to trading it...
Well that depends if he has some good stamps on it.
Will see if I can find a mar'eh mokom.
