Dickinson paper

Dickinson paper was a patented creation of papermaker John Dickinson. It consisted of long silk threads imbedded in sheets of paper as a security feature. It is found in Swiss Strubels and the British 10d and 1/- of 1847 and 1848. The threads are most visible when a stamp is held to the light or placed in watermark fluid. Benighted people have pulled out threads on occasion, which translates to a damaged stamp.
