I just make a series of change requests to use the same denomination name in the title and to add size information to the title.
Thank you for checking and finding the two listings as well as making these requests!
I canceled mine, I may request some small changes to improve the page of the larger coin.
It is a very interesting and unexpected outcome to me, though a size reduction to save on metal in a time of high inflation makes sense.
My assumption would be that the smaller coin was introduced after the larger one had been released already, finding any evidence on the time line of the release of these two versions would be interesting.
Besides coins I love geometry. The avatar consists of each of the 35 hexominoes used precisely once. With the 5 large yellow shapes placed like this, the solution for tiling the remaining 30 hexominoes is unique.
