Despite the current low mintage figures of most 2021 coins, I'm coming across hundreds and hundreds of all denominations of standard 2021 coins in circulation except the $1 MOR.
I expect the mintage figures to rise significantly when the next RAM annual report comes out.
I have not seen or heard of any 2021 MOR dollar coins found in circulation. Probably due to those darn A-Z coins being released instead.
