What is a niche interest or hobby you'd personally like to see represented more on Lemmy
For example, I used to follow a lot of subreddits for individual YouTube content creators, however, Lemmy doesn't really have the size or culture to support this currently.
Ancient coins. There's a sub on Lemmy but it's sadly unpopulated. I miss being able to interface a bit with other collectors, but fuck my ass if I have to go back to Reddit for that.
I digged down in what coins (they overlapped usually IIRC) had the highest probability of have being manipulated by jesus or the supposed apostles. Wasn't that expensive if my memory is right to get a bunch with a high probability.
In that case you'll be looking at Judean Prutahs or Leptons (the fabled "widow's mite"), and denarii of Tiberius which are known as "tribute pennies". Most of them are quite affordable if not incredibly impressive.
