You’re right, I think, about the appeal of Swiss coins. I really hadn’t thought of it that way, but type-collectors of Swiss coins are so easily satisfied, so the field is wide open for us date-collectors.
As you say, assembling long date-runs is an attraction of Swiss coinage. And the age of the coins in actual circulation…because the coins have remained so much the same, very old coins can sometimes be found in pocket change. I know the first time I got an 1884 20-rappen in everyday pocket change—as a boy—I thought it was some sort of a trick!
The designs too have a special appeal. The wreath-work is superior, and the allegories have a particular pull as well. (When I first encountered Swiss coins, American circulating coinage was shedding its last allegorical Liberties, and I hated that.) (But let me revisit the subject of “American allegorical Liberties” elsewhere, because what I’ve just written is not technically true.)
I also enjoy the terseness of Swiss coinage, especially in contrast to my own American coinage, which is sometimes…well, sometimes over-talkative.
Then there’s the fascination of Swiss ½-, 1-, and 2-franc coins, and their 40 years (1927-1967) as living fossils of the LMU….

Hope one day you get your 1896!
