Housed in the Deshengmen Gatehouse, this museum is an interesting spot for a quick visit by travelers who are into ancient currency. Packed into three rooms are the various coins, shells, and paper used as money over China's 5,000 years of history. Those with kids might find it a fun visit, since the imposing gatehouse that houses it is a bit castle-like, with its many dark nooks and crannies. Outside are stalls where vendors show how easy it is to actually mint money nowadays, with examples available for purchase as souvenirs.
