MONEY!!!! Just kidding. Well, I actually do have a decent little collection of coins from various parts of the world, my favorites being an old 2 shilling piece and a modern coin from New Zealand that features an image of a face with traditional indigenous tattoo designs.

Star Wars memorabilia, mostly the vintage toys or anything Darth Vader related. It's all scattered about my spare room right now, trying to find the time to rearrange everything into some semblance of order.

I collect shot glasses from places I've been and marvel stuff

I collect tea pots and other tea accessories. I don't just collect them, however, I use them as well. Some are displayed in a cabinet, but others are kept away. About twice a year I switch some of the pieces.

I used to display it, but I learned that human skulls make people feel uneasy.

Sadly I "collect" most everything, (so far the only thing mentioned by anyone here that I don't have several to hundreds of are the "wooden hand planes" I also have dirt/grass/rocks and water from places I have traveled and those that friends have brought me back when I couldn't go. They are in pretty jars/bottles in my china cabinet. I am not quite hoarder status yet, but my youngest child "the minimalist" is really nagging me.

Pigs. It started with a hand-carved wooden pig with wings, wearing a Santa Suit. They've all been gifts. One of my nephews gets me the same birthday card every year. "If you're happy and you know it, clamp your hams." It's a fairly small collection, but it's the only knick-knacky type thing I do, and it's actually completely out of character.

I used to collect comic books. I haven't in a long time. I still have boxes of old ones that I am giving to my nephew. They are probably worth some money.

Was dust one of the categories you were thinking about? lol

After rocks, fossils and stone artifacts I collect almost nothing else other than silver coins.

I used to collect baseball cards until they became worthless. At least the ones I had from the time I grew up are 99% worthless. Cards from the 80s and 90s and sooner are probably worth on average . 1 - . 3 cents a piece. The money is in the cards from before the 60s and 70s really. I think the 50s has the most cards collectively that are expensive. The most expensive card ever is Honus Wagner from 1909 - 1911. It's worth almost $3m now. I used to just enjoy it, but that stopped at some point.

teapots

I have a collection of horses, 4 to be exact. They have a pasture and can be viewed up close, or from the road.

Books, lots of books, shell and rocks we find, but mostly books. Shelves of them by author and series.

I used to collect die-cast cars; still have a few. That started mainly because a house I once bought had a room with shelves covering half of one wall and I needed something to put on them.

Both my collections are virtual. I collect Kindle books, and my wildlife/bird photographs. I store photos and videos on Google Drive.

I started collecting old woodworking hand planes, but they're not just to look at. I also use them. After I while I grew tired of collecting them, and stopped buying every one I found. I do still have quite a few though.
