I collect mother if pearl "gentleman's gear". Things like pocket knives, cigar cutters, letter openers, shoe horns, shaving appliances, combs.

Old film cameras - I have hundreds.

I collect watches. Mostly mechanical ones with no electronics. Of all types.

I also collect Mad Men era cigarette holders / lighters, some artwork, and some antiques.

I collect comic book memorabilia, Yankee Candles, masks, pens, Starbucks mugs, Greek museum-quality replicas, a cool bar of soap, and Hard Rock Cafe t-shirts and pins.

I collect Kindle books I don't mind rereading often.

I used to collect knives, and I still sort of do. When I was little I was an accurate knife thrower, and in college I had curved daggers, a switchblade, etc.. These days I don't risk even carrying a penknife.

I stockpiled out of season cloth material bought at steep discount, so I could sew anything, any time it struck my fancy.

Also rocks, fossils, and polished stones, but couldn't bring them overseas.

I collect Books and Space related stamps.

I collect Owls of and kind. Shirts, pictures and jewelry are what I have the most of.

I started off on my first honeymoon collecting elephants. I don't have room for all of them, they're in storage. I seem to have a fairly large rock collection. I'm not really sure how some of them got here. I have collections of weather related things, maps and globes, chickens and fish.

I collect debt. My collection is HUGE, especially when compared to my income.

I collect crystals, also still got my Stamp Album from the 1970's.

I used to collect chessboards. I have about 30 of them. Until recently they just sat in my attic or in boxes in the garage. I recently built a display case, but it only holds 3. I've got my favorite 3 displayed now, but I might build more in the future.

I used to collect antique keys - I had more than a hundred, but I decluttered a few years ago and gave them all to another collector.

I used to collect American Indian sand paintings, southwest decor to decorate my home. Home is long done. Used to have over a hundred t-shirts from traveling and concerts. Stopped buying those too. Trying to declutter.
