fin 
O.E. fin, from P.Gmc. *finno (cf. M.L.G. vinne, Du. vin), perhaps from L. pinna "feather, wing," or, less likely, from L. spina "thorn, spine" (see spike (n.1)). U.S. underworld slang sense of "$5 bill" is 1925, from Yiddish finif "five," from Ger. fünf. The same word had been used in England 1868 to mean "five pound note" (earlier finnip, 1839).
