When were serial numbers first applied to banknotes in the way that they are in this banknote, i.e. in the bottom right-hand corner? http://www.ushmm.org/lcmedia/photo/lc/image/25/25689.jpg
my book English paper money states from 1808 the dates and serial numbers were printed on notes,but printed in different positions then the one you show.i see notes from 1918 with the numbers bottom right hand corner.
Pam West has one from 1913 with the number in the lower right. You may want to look through her site for this and your other question about Edwardian era notes.
