What font is this number 5? Looks similar to gill sans

Classification: 

i'm not trying to produce counterfeit money... just trying to work out a font similar for a design I am working on.

the 5 looks similar to gill sans however doesnt work with the numbers 10 and 20.
I am thinking now maybe its a different typeface all together?

anyone got any ideas what it could be? preferably the number 5?

Many thanks

I'd think all bank notes would have proprietary typefaces to make counterfeiting more difficult.
