Postage Due

This is a special stamp used to collect a fee where a letter does not have enough postage on it to get it delivered. Getting these, especially the high values, can be tricky as you need to send it, without a stamp, from somewhere where you know an exact amount will be owed to delivery. Cover dealers have even been known to post covers from abroad to try and get the right postage due stamp.
