With the exception of Additional Halfpenny marks 1813-1839, there was little need for “charge” or “surcharge” marks before 1840 as postage was usually paid by the recipient. However after the introduction of Uniform Penny Postage there was more widespread need for this type of postmark. Before 1840 there were a few instances of the use of marks to denote “postage due” but these were mainly confined to the major cities and no marks of this type are known used from the county before the introduction of Uniform Penny Postage.
