Yes, you can print your very own money featuring the face of the Tenth Doctor. These phony banknotes came about thanks to the art department of the series. In the 2006 episode, “The Runaway Bride,” the Doctor accidentally makes an ATM break with his sonic screwdriver. It starts spitting out cash, and the crew decided to make said cash feature the faces of David Tennant and producer Phil Collinson.
I recommend printing a stack and carrying them around with you next time you wear your Doctor Who costume.
See the £20 note with Collinson after the break.
