The 12C in silver? That's a steep mountain to climb. Congratulations! It sounds like you're at or near the summit and it should be mostly downhill from here.
That coin has the right wholesome look for a well circulated piece, in my opinion.
The
rarity alone would make it worth having, but
rarity combined with decent
eye appeal is a sweet cake with just the right frosting on it.
Sorry for the lame pastry metaphor. I tried for better but came up short.
Rarity and
eye appeal are like peanut butter and jelly? No, that's worse.
Anyway, you know what I mean.
Good job.
