It will be interesting to see whether the coins will still be issued, and if not, if pattern strikes exist. When asked the Manx Wildlife Trust, which was promissed a part of the proceeds, commented that unfortunately the coins are still being developed at Tower Mint. They don't have a reliable idea of when they will be issued but hope to in the future be able to sell them in their shop on the island.
I like it that all of the animals depicted on the coins actually live on the Isle of Man. The designs are nice too, certainly the ones for the 2020-dated coins. It appears to me that 2 different artists made the designs for respectively 2019 and 2020.
