Please note, 20 circulation 50ps are listed at the bottom of the table and their mintage numbers are given as UNKNOWN. So, each year it has a new mintage number showing the amount of the coin that was struck that year.
For example, as you can see, the Britannia design 50p was issued multiple times but each year the coin was struck with a new date. For anyone new to coin collecting, the mintage number is the number of copies issued of a particular coin. We have arranged them in order of rarity using their mintage number. The list in the table below covers every design of the new coin that has been manufactured since the size change in 1997.
