Everyone is going on about low mintage coins all the time, what about high mintage ones.
The one that comes to mind is the US cent I think most years several BILLION are minted and some dates are over 10 billion coins minted if you combine all the mints.
Average numbers have trended downwards from 9 billion in 2015 to about 6 billion in 2020. This is well below the 2000s with some 10.3 billion issued in 2001. Even crazier was 13.6 billion coins issued in both 1994 and 1995. Who really needs that many coins, thats like 70 coins per American at that time.
Also interesting are the most common coins and dates in your country.
Mine is New Zealand and we only have had between 3 and 5 million people, yet the great recoinage of 2006 saw an insane 326 million 10c, 20c and 50c coins issued or some 80 per person for the population then (4.1 million).
Highest single date mintage of a coin - Predecimal - 1964 penny 18 million (Population 2.4 million)
Decimal before 2006 - 120 million 1967 1 cent coins (2.6 million)
After 2006 and all time - 10 cents 2006 - 140,200,000 (4.1 million) or 45 coins per person!
