This set contains two fifty-pence coins: one issued in 1969 and one issued in 2019, and celebrates the 50th anniversary of the denomination. The 2019 coin is in Brilliant Uncirculated grade, while the 1969 coin has been taken from circulation and is in a minimum of Very Fine condition.
The mint says about the set:
"1969 was a momentous year for Britain. Concorde took to the skies, Monty Python hit our screens and a radical new coin was put into circulation to replace the ten-shilling note. As the 50p turns 50, we mark this milestone moment for one of our best-loved coins with a special anniversary set. An original historic 50p from the year of its launch, featuring Christopher Ironside’s classic Britannia design, is paired with a 50p from 2019, celebrating half a century in service for the world’s first seven-sided coin."
