Revenue stamps

I uncovered some old legal documents lately. They were great! Some of them - comprising Indentures, Deeds and Mortgage Conveyances - carried revenue stamps and marks from the era of the Straits Settlements. 

A five-dollar or even a one-dollar revenue stamp isn't worth much in today's world but back in those days - one of the documents dating back to 1898 - it must have cost an arm and a leg to buy. But they were compulsory for affixing on documents to make them legal. 

Great addition to our historical records and knowledge!
