This note, consisting of a 2 cents stamp on the left and a 3 cents stamp on the right, roulettes down the center for ease of separation. It is probably the only currency note which could be torn in two and the two parts were still legal tender at different denominations.

The note is not in my collection. Scans courtesy of Dr. Kavan Ratnatunga. Additional information about this note can be found on his website.
