The first organised collecting hobby. Sets, catalogues and specialist dealers - all the infrastructure of modern collecting - appear within a decade.

Companies insert stiffening cards into packs and print them with images. Series, completion and the drive to collect all 50, invented deliberately as a sales mechanic.

The Honus Wagner card is withdrawn because he objects to his image promoting tobacco. Scarcity created by accident drove huge resale values.

The thing you can only get by being there takes hold - stadium giveaways and attendance exclusives.

The album-and-sticker format spreads across Europe. A completing-the-book culture still running 70 years later.

Mattel introduces die-cast cars with a hidden chase mechanic. Roughly 500m cars a year later, people are still searching store pegs.

The modern toy licence era begins. Kenner's line - sold as an “early bird” certificate before the figures existed - invents pre-order collecting.

The first modern TCG. Invented the booster pack, the rare/uncommon/common system, and the secondary trading market for cards.

The 1990s collecting supercycle. Cards, Game Boy, Pokédex and virtual pets - collecting goes fully global and fully digital simultaneously.

A stuffed animal with a code that unlocks a virtual pet. Physical purchase as digital access - the first mainstream phygital collecting product.

Stuck at home, bored, nostalgic, with disposable income. Trading card sales explode.

Passes US$5.1bn in revenue. A blind box figure with no narrative becomes the must-have product of the year.

Third-party services assess a card or comic's condition, seal it in a tamper-proof case, and assign a numeric grade.

A PSA 10 (Gem Mint) can be worth 10-50x the same card ungraded. PSA leads with 71.8% market share; Beckett and CGC cover the remainder.

In 2025, 26.8 million items were graded across all services, up 32% year on year - at peak demand in 2021, PSA temporarily stopped accepting new submissions.

Video-first commerce where the entertainment is the point.

Whatnot is the dominant platform - US$8bn in GMV in 2025, more than doubling year on year, with 20 million new accounts created in 2025 alone.

'Breaking' sits within this: a host buys a sealed case of cards, sells "slots" to viewers before opening it on stream, then ships each viewer their cards.

Rip and ship is the simpler version: buy a pack, watch it opened live, receive what's inside.

Platforms where buyers and sellers meet, with authentication and price discovery built in.

eBay remains the dominant marketplace for cards, comics and general collectables.

StockX (US$3.8bn valuation) and GOAT handle sneakers with authentication on every transaction.

Goldin Auctions and Heritage Auctions handle the premium end: signed memorabilia, graded cards, rare comics.

A physical card or collectable is professionally authenticated, then stored in a secure third-party vault.

The owner receives a digital certificate representing the asset - tradeable and transferable without the item ever moving.

Courtyard (courtyard.io) is the leading example: it bridges physical and digital collecting, enabling fractional ownership and instant settlement without the risks of storage or shipping. Unlike NFTs, the underlying asset is real and independently valuable.

Every core collecting mechanic - the blind box, the loot box, the pack rip, the gacha pull - is, structurally, a bet. You pay money for a random outcome. The difference between this and a slot machine is one of framing and social acceptability, not mechanism.

The UK, EU, US, China and Australia are all at various stages of legislating or scrutinising loot boxes and chance-based mechanics targeting children.

"Junk wax" is the term from 1990s sports cards - when manufacturers flooded the market to meet demand, destroyed the scarcity that made the cards valuable, and triggered a decade-long collapse.

The lesson hasn't always been learned. Scarcity only works if it's real. Overproduction kills the category from the inside.

Pop Mart's share price fell sharply in early 2026 as growth concerns emerged after the initial Labubu craze.

While the macro trend of collecting endures, individual properties spike and fade.

Designing a collectable around a single character or trend is a different bet to designing one around a durable mechanic.

Taylor Swift's The Tortured Poets Department (April 2024) launched with multiple vinyl variants, it was exactly the same content just with a variety of different colours and finishes.

There are many who feel like this is exploiting fans, leveraging the intense parasocial attachment they have to the artist and their desire to own everything.

The question of where "clever marketing" ends and "fan exploitation" begins is one regulators and fan advocates are now asking.

Pick your mechanic

Blind/random reveal, set completion, tiered rarity, or event exclusivity - choose one as your primary engine, then add a second. The best lines layer mechanics: a blind box (random reveal) inside a series (set completion) with a secret chase figure (tiered rarity). Pop Mart does all three. Sticker albums do two.

Design your rarity architecture

Base / Uncommon / Rare / Ultra-Rare / 1-of-1. Every tier needs to be genuinely worth having, not just a diluted version of the rare. The base item is what most people get - it has to deliver. The 1-of-1 is what everyone talks about - it creates the legend.

Decide: IP first or mechanic first

You can build the mechanic around existing IP (Panini + FIFA, Pokemon + card game) or build the IP around the mechanic (Pop Mart's Labubu had no lore when it launched). Both work. IP-first is lower risk on acquisition, higher risk on licence dependency. Mechanic-first is harder to launch, but you own it entirely.

Build in the social layer from day one

The reason to trade is the reason to talk. Design the product so that duplicates have value - for swapping, gifting, or trading up. A collecting mechanic without a trading mechanic is a vending machine. A collecting mechanic with a trading mechanic is a playground and the playground is where the fandom lives.

Make the secondary market work for you

A healthy secondary market increases primary sales - it tells prospective buyers that what they're buying holds value. Design for gradeability (consistent dimensions, quality packaging, clear rarity markings). Make prices discoverable. Don't fight the resale economy; it's free marketing.

Create physical touchpoints

Where can people experience, discover and collect in person? Stadium exclusives, store events, convention drops, flagship retail. The physical moment is the memory anchor.

Plan the series, not just the launch

The first series is a test. The second series is where you find out if you've built something durable. Design the IP or theme to evolve: seasonal updates, crossover editions, retired designs that create scarcity in back catalogue.

Get the regulation right before it gets you

Build odds transparency in from the start. Design age-appropriate mechanics for the age group you're targeting. Don't use dark patterns. The brands ahead of the regulatory curve will have a significant advantage as the rules tighten across Europe and the US over the next three years.
