What is 5 series 1953B us demand note worth with no In God we trust on back?

In average condition, face value only. It might retail for up to $8 if only slightly worn.

To clear things up, this is generally called a United States Note rather than a Demand Note. Also the motto is In God WeTrust, just like on all modern bills and coins. The motto was first added to bills during the late 1950s and early 1960s as a political move to counter the supposed threat of "godless communism", so any older bills without the motto (such as yours) are NOT errors.
