What does 'Not worth a tinker's dam' mean?
Meaning: This means that something is worthless and dates back to when someone would travel around the countryside repairing things such as a kitchen pot with a hole in it. He was called a 'tinker'. His dam was used to stop the flow of soldering material being used to close the hole. Of course his 'trade' is passé, thus his dam is worth nothing.
