rareness वाक्य

There are coins that have all of these fancy claims of rareness and value that are not even really coins at all-you're spending $ 20 on an utterly worthless piece of metal that costs less than $ 0.05 to produce and will have PRECISELY zero value the nanosecond after you take it out of the envelope ! " We'll take your old jewellery-just post it to us, we'll assess how much it's worth and send you back a cheque for the full value ! " . . . so wait-you'll accept any amount they decide it's worth ? $ 1 is OK for that antique gold wedding ring?
