The new polymer 20 GBP note will be issued February 20, 2020, and will feature artist JMW Turner. https://www.bankofengland.co.uk/banknotes/polymer-20-pound-note Since Britain is ahead by a few hours, the 20 pound note will be in circulation very soon.
I wish I knew about this sooner as I was in London at the end of December into New Years and just at the airport in Heathrow yesterday. I should have saved an example of the current design. I don't care for the polymer tens or fivers. The paper ones are superior in feel, quality, and overall design.
I actually like polymer notes for some reason. Hong Kong also did this some few years back with their dollar.
Ugh, wish it had better engraving, love The Fighting Temeraire, I have a hand painted copy of it, several other great works as well from Turner...
I got 3 from the ATM today, already used so I will have to wait and get some Unc from my bank. They sure don't beat the £434 in old money I found in a house clearance yesterday though
