Elizabeth II, 20 Pence Cover & 2000 20 Pence
In 1982 they issued the first 20 pence coin. But in Victorian times they issued a Double Florin in Sterling Silver which was almost crown sized, but had the same exact face value as our current 20p.
I have found some stamped covers celebrating the first day of the New 20 Pence coin. They have the Royal Mint special cancellation and are numbered out of a total printing of only 800 covers. I decided to make it even more interesting and have combined the cover with a Brilliant Uncirculated Millennium 20 Pence coin. But please remember we have very few covers and they were posted 37 years ago!
