Those minerals and fossil are awesome @aetsen ! I used to collect them a lot in the past as well, but haven’t really added anything lately. And I’ve only searched for minerals and fossils like two or three times in my life, once in France and two times in Germany.
Here are some pictures of my collection (ignore the huge piles of dust… 
):
Most of the first, third and fourth pictures are bought on vacations or in musea. But the second picture mostly consist of things I found myself (except for that one compartment at the bottom-left).
Ugh… I’m having this nasty cough now after opening the drawers to take photographs… 
Really need to dust them off…
As for another collection of mine:
Full list with links to individual pictures can be found here.
And I also collect one of each rarity (including OCG and misprints) for Yu-Gi-Oh. (Not really up-to-date, got about ten new ones I think.)
