the adam smith 20, and the 50 — featuring the portraits of manufacturers matthew boulton and james watthdrawal of the boulton and watt £50 note also marks a change in 300 years of history. that�*s because it�*s the end of paper banknotes in circulation. for the first time, the entire bank of england collection will be made of polymer. 2.50, then, please, lovely. over the road in a cashless cafe that was once an old banking hall, the new plastic notes get a mixed reception. so they�*re a bit slippery. they're a bit slippery. they're quite, you know, difficult to keep hold of, really, yeah. notjust because you�*re spending them? no! - they laugh. yeah, feels a little bit cleaner and a little bit less concerned about it ripping in my pocket. i'm not sure, but looks like a plastic one looksj to be much better. very smooth. and i think i probably would like the plasticj one than the paper one. if you find you still have some paper banknotes after friday�*s deadline, you can queue here at the bank of england, at your own bank, or at some post offices to exchange the old notes. kevin peachey,
