The Royal Mint should reproduce Brillant Uncirculated Kew Garden 50p Coins

Recently The Royal Mint decided to reproduce Brillant Uncirculated Beatrix Potter 50p coins from 2016. This was apparently due to popularity amongst consumers and not as a source of increased revenue.

If these coins can be reproduced then why not other popular coins that are only available from unofficially outlets at a severely inflated price. 

The Kew Garden is one of the most popular coins amongst collectors and as such should be reproduced to allow collectors to complete their collection at a reasonable cost.
