Hello everyone! I got this silver ansei ichibugin today (Is that the proper term?) and I have no idea on how to find the correct variant since I am in no way experienced with these types of coins, therefore I need help with this one. If anyone more knowledgeable with these could help me I would be extremly thankful.
Thank you both very much! Maybe there should be a part in the comments that describes this method of identifying variants, Could @Sjoelund possibly make one? I know he makes those really useful pictures describing variants.
I made a modification request with in the comments:
Explanation for the year lines Aa, Ab, Ac, … Gg:
The left drawing shows the positions of stars A, B, C, … G and a, b, c, … g.
The right drawing shows an example for the stars that are placed upside down on a Bf variety coin.
This is only a start, as obviously there are more varieties.
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.

Thanks for your nice words, but that kind of coin is completely outside my competences.
I replaced the stars with proper sakuras in my drawing. Can someone confirm that the sakura I marked with a Z is placed correctly?

No Z/z is when all sakura on a side are in normal position (most often a bad sign but it seems there a 3 variants were this is the case).
Thank you for the explanation, Idolenz! When date lines are added to specify varieties for 1 Bu “Meiji Ichibugin” and/or 1 Bu “Tenpō Ichibugin” then I can adapt my drawing accordingly.

P.S. there seems to be an error or deliberate fault in Hartill's catalog where I extracted the key from. If you follow the logic of the ordering, the second K/k should be an L/l.
