An impressed duty stamp is a form of revenue stamp created by impressing (embossing) a stamp onto a document using a metal die to show that the required duty (tax) had been paid. The stamps have been used to collect a wide variety of taxes and duties, including stamp duty and duties on alcohol, financial transactions, receipts, cheques and court fees. Usage has been worldwide but particularly heavy in the United Kingdom and British Commonwealth.
Impressed duty stamps are to be distinguished from adhesive revenue stamps which are applied to documents in the same way that a postage stamp is applied to a letter.
