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.

I collect fish and love displaying them.

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 pressed pennies, but they seem to harder to find now.

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.

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

I collect books on organized crime and lost baby items I find on the ground...rattles, bottles, bibs,pacifiers, toys- you name it...very funny story about how this started....I just wanted a collection nobody else in the world would have...it's in a box in the other room.

teapots

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.

Broken hearts.... Lol Just kidding, I don't collect anything. Eventually everything starts irritating me, and I throw all the junk away

I used to collect a lot of things: old pulp science fiction magazines, WW2 German militaria, comic books, anything to do with the TV show "Lost in Space." and so on. And then I realized that all of these great things were just boxed away (being out in the open can fade colors, making it all less valuable, after all). Occasionally, I would look st my stuff briefly, before boxing it all up again. One day I realized this was crazy, and I started selling the stuff off. Whenever someone asks about collecting stuff, I always say "My collection consists of what I haven't sold yet." If I got back into collecting, I'd collect Soviet or East German militaria, because the stuff looks interesting, the prices are relatively low, and because it's all so common, there are hardly any fakes on the market.

A good old classic scotch colletion never fails to have around

I used to collect glass bottles and kept them on a shelf in the front room before my ex wife put an end to it. I had an unopened coke bottle from Iran from my brother's deployment. Recently I've been turning bottle caps from drinks I like into magnets on my fridge.

brass bells in the shape of girls , blue china plates with depictions of life and paintings and yes they are proudly diplayed

I have a collection of split bamboo fly rods. And several banjos, both 4 string and 5 string.

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

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

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

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.

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

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

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.

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