Think you've seen the strangest corners of the collecting world? We're just getting started.
Part 1 introduced sugar containers, Victorian coat buttons, and cereal boxes, and the passionate communities that have built entire worlds around them. It turns out that was only the beginning. Our team has spent more time digging through the 30 million+ items on Collectibles.com, and the deeper you go, the more extraordinary it gets.
Part 2 goes further. We're talking calendars, minerals, and a category that holds a deeply personal place in one of our founders' hearts, one that reminded us why this platform exists in the first place.
Every object has a story. Every collection has a community. And we're on a mission to spotlight all of them, every single category on the app, one edition at a time.
Before you dive in: Haven't read Part 1 yet? Start there first. And if you've got an unusual collection of your own, send us an email at info@collectibles.com; and you might just find yourself featured in a future edition.
Now, let's dig in!
1. Salt & Pepper Shakers
Vintage salt and pepper shaker collecting is a surprisingly deep rabbit hole. From fine porcelain figural sets crafted in mid-century Japan to Art Deco chrome diner pairs and novelty ceramic sets, the variety is enormous, and the best examples are small works of decorative art that display beautifully as a group.
Collectors typically focus on a specific style, era, or theme, which means the hobby has real structure to it. Affordable entry points, endless variety, and a collecting community that takes its figural ceramics seriously. Don't underestimate the shakers.

2. Buttons
Clothing buttons have been collected since the 18th century, and the category has a depth that catches new collectors completely off guard. Hand-painted porcelain buttons, stamped brass military buttons, carved ivory and bone examples, and early plastics each represent a distinct era of materials and manufacturing history.
Collectors who specialize in decorative examples are known as pictorialists, and the expertise they develop, identifying makers, periods, materials, and methods, rivals that of any antiques specialist. One of the oldest collecting categories in existence, and still one of the most rewarding.

3. Calendars
Vintage calendar collecting sits at the intersection of graphic art, advertising history, and cultural nostalgia, and it's deeply underrated. Pinup calendars, Art Nouveau illustrated almanacs, Depression-era promotional calendars from long-gone local businesses, early photographic examples: every one is an annual snapshot of design trends, printing technology, and visual culture.
Most people threw them away at the end of the year. The ones who didn't leave behind artifacts that now tell the story of how an era saw itself. That's worth saving.

4. Belt Buckles
Western and decorative belt buckles have a collector community as passionate as any on this list. Hand-engraved sterling rodeo championship buckles, Native American silverwork, military examples, Art Nouveau brass pieces, the range is extraordinary, and the best examples are wearable sculptures crafted with a level of artistry that makes them as impressive when displayed as worn.
Championship and commemorative buckles carry real provenance: they were earned, awarded, and worn at specific moments in history. That story travels with the object. Few collectibles can say the same.

5. Stones & Minerals
Every mineral specimen is unique. Tumbled gemstones, polished jasper, raw meteorite fragments, and rare crystal formations, each piece took millions of years to form, and no two are ever exactly alike. That's not marketing language. It's geology.
The price range runs from a few dollars to thousands, which makes this one of the most accessible categories on the list for new collectors, and one of the most scientifically fascinating for experienced ones. Natural, beautiful, and entirely unrepeatable.

Bonus! Lunch Boxes
Few collectibles trigger nostalgia quite like a vintage lunch box. The lithographed steel kind, the ones that dented when you dropped them and smelled faintly of thermos soup, were produced from the 1950s through the 1980s in thousands of licensed designs, tied to every TV show, cartoon, and pop culture moment of the era. The Lone Ranger. Star Wars. The Dukes of Hazzard. If kids loved it, it ended up on a lunch box.
What makes them genuinely valuable is the same thing that made them disposable: they were used hard, every day, by children. Surviving examples in excellent condition are rarer than most people expect, and a pristine first-run 1954 Hopalong Cassidy box, widely considered the lunch box that started the craze, can fetch hundreds of dollars from the right collector. Thermoses matter too; a box missing its original thermos is worth significantly less to serious buyers.
The category spans metal, vinyl, and plastic, and collectors typically specialize by era or theme. But whatever the focus, the appeal is the same: these were objects of pure childhood joy, mass-produced and mostly lost to time. The ones that survived are tiny, battered, beautiful pieces of mid-century Americana.

Every Collection Tells a Story
Six categories in, and we've barely scratched the surface. That's the thing about collecting, no matter how niche it seems from the outside, every category has its obsessives, its experts, and its hidden depth. Belt buckles earned at rodeos. Buttons that predate photography. Lunch boxes that outlasted the childhoods they came from. The objects people choose to save say something real about what mattered to them, and now, to you.
We'll be back with Part 3 soon!. In the meantime, explore all of these categories and thousands more on Collectibles.com, and if you've got a collection that belongs in this series, you know where to find us.
