Got them all so far except the yale in gold.
Really like the series as it combines the best of both worlds with you getting a "cheap" bullion coin but as we have seen with the Lion and Griffon the collectors are willing to pay a high premium for those.
I wonder if they do something like "the kings beasts" or "queens beasts 2" if they are done with it.
Would probably be great for flipping in a couple of years then
