A history of inserts, from Diamond Kings to Refractors

Published July 15, 2026

The insert card was invented in the middle of the junk-wax era and then, ten years later, killed it. That is the compressed version of this story. The longer version is a decade of card companies trying to solve the same problem: how do you keep a hobby interesting when the base cards are being printed by the truckload and everyone in the family owns three of everything. Every solution the industry landed on became more sophisticated than the last, until the solutions themselves were the product and the base cards were the packaging.

A history of the inserts follows. It is not a checklist. It is the arc from 1982 to 1994, told through the six or seven insert experiments that mattered, and framed around a single question: at what point does an "insert" stop being a novelty inside a mass-produced set and start being an entirely different economic object? Once you can answer that question you also know why the JW50 stops where it stops.

1982 to 1987, the subset era

Before "insert" was a hobby word, card companies produced subsets. A subset was a themed run of cards inside a base set, printed at the same rate as every other card in the set, distributed identically, and pulled at the same frequency. Donruss's Diamond Kings, launched in 1982 and continued every year through the junk-wax era, is the canonical subset. Twenty-six cards per year, one per team, painted portraits by Dick Perez, positioned as cards #1 through #26 of the base Donruss set. They were collectible because they were distinct, not because they were rare. Every kid opening a 1985 Donruss pack got roughly the same number of Diamond Kings as any other card.

Fleer's Star Stickers, Topps's All-Star subset, Score's Dream Team, Donruss's Rated Rookies, and the various in-set award and league-leader cards all operated on the same principle. Themed. Distinct. Not scarce. These were subsets, not inserts. They set the visual expectation for what "special cards inside a set" could look like, without ever manipulating pull rates.

Two 1985 Topps products crossed the line early. The Topps Glossy Send-Ins were 22 cards of stars, sent by mail to collectors who redeemed proof-of-purchase points from wax packs. Because you had to redeem for them, they were not distributed by pack. The 1985 Topps 3-D was a similarly experimental oddball. Neither was a modern insert in any real sense, but they demonstrated that Topps was willing to produce a parallel product distribution channel to collectors already invested in the set.

1990, the hologram revolution

The insert card as the hobby now understands it arrived in 1990, in two products released within months of each other. Neither is a sports card, and both are anchor exhibits in the non-sport bloc of the JW50.

Impel's 1990 Marvel Universe Series 1 debuted the first widely-distributed pack-inserted hologram cards. Five cards, numbered MH1 through MH5, seeded roughly one per box. Kids opening 1990 Marvel Universe wax pulled the Cosmic Spider-Man MH5 or the Silver Surfer MH2 and understood immediately that they were holding something different. The holograms cost Impel roughly forty cents apiece to produce, at a time when a base card cost fractions of a penny. The economics of the hologram were the economics of a chase: you could not force one out of a fifty-cent wax pack, you had to be lucky, and the card companies knew that scarcity created demand.

Pro Set's 1990 Football included the Lombardi Trophy hologram card, distributed as an in-pack chase at similar rarity. Both products taught the industry the same lesson: put one physically-distinct card in the pack, price it higher than the base cards, and collectors will pay for the privilege of chasing it. Neither the Marvel MH holograms nor the Lombardi hologram is expensive today because Impel and Pro Set were both themselves heavily overproduced, but the cards changed the industry's understanding of what a pack could contain.

1990, Upper Deck Heroes and the first modern autograph

Later in 1990, Upper Deck's Baseball Heroes subset produced the AU1 Reggie Jackson. Signed by Jackson himself, numbered by hand to 2,500 copies, and inserted randomly across the entire Upper Deck 1990 High Series product. It is the first meaningful in-pack, on-card, serially-numbered autograph in mainstream trading cards. Every autograph card the hobby has produced since descends from this one.

The AU1 is not in the JW50. It is documented in the methodology as a post-era exclusion, for the same reason SP, Finest, and the Stadium Club Beam Team are excluded: the auto invented an entirely new economic category. It is a signed collectible that happens to be produced on cardboard, distributed at scarcity per individual signing volume, and traded on the signature and the print run rather than on the image or the story. The auto card is not a junk-wax card. But it was born inside a junk-wax product, and understanding when it was born clarifies the exact point at which the era's economic model changed.

The commercial logic Upper Deck introduced in 1990 with the AU1 became the entire industry within four years. By 1994 every major manufacturer had an autograph program. By 2000 signed cards were the primary revenue driver of the whole hobby. It all starts with Reggie.

1991 to 1992, the seeded-scarcity era

Once the industry had seen holograms and autos work, the next two seasons compressed years of experimentation. Every major manufacturer added inserts to their product lines. Donruss Elite (1991) seeded 10,000-print serial-numbered star cards at approximately one per case. Score's 1991 The Franchise inserts. Topps's 1991 Desert Shield parallel of its base set, physically identical to the base cards except for a metallic gold stamp on the front, printed in only 6,800 sets and originally distributed exclusively to United States military personnel serving in Operation Desert Shield. Desert Shield is one of the only parallels of the era with a documented print run. Chipper Jones's rookie #333 in Desert Shield sits at exhibit #20 in the JW50.

1992 was the year the industry crossed over. Topps's 1992-93 Stadium Club Basketball Beam Team inserts, die-cut, all-foil, seeded one per twenty-four packs, are the inflection point. The Beam Team Jordan is one of the most visually iconic basketball cards of the entire decade. It is also not in the JW50, for the same reason Reggie AU1 is not. The Beam Team is the first true modern chase insert: engineered scarcity from the manufacturing floor, priced on the mechanic itself, and produced at a materially different unit cost than the base cards in the same product.

1992 Bowman baseball dropped its own foil-parallel inserts of a subset of the base cards. 1992 Pinnacle debuted its Team Pinnacle die-cut dual-portrait inserts. 1992 Score arrived with its Dream Team. Every major manufacturer was now shipping inserts as a core part of their base products.

1993, the end of the era

Two 1993 releases mark the boundary the junk-wax era ends against. The first is Upper Deck's 1993 SP set. SP introduced the modern foilboard premium: high-gloss chromium foil card fronts, printed at scale, priced at roughly triple the standard base card price at retail. The 1993 SP #279 Derek Jeter rookie is arguably the most iconic card of the 1990s. It is not in the JW50, because it is not a junk-wax card. SP invented the premium set format that every high-end product of the last thirty years descends from.

The second is Topps Finest, released a few months after SP. Finest introduced the color-shifting refractor parallel: every base card in the Finest set had a rarer refractor version, distributed at 1:9 packs. The 1993 Topps Finest #110 Ken Griffey Jr. Refractor is the first meaningful refractor in the hobby. It is also excluded from the JW50. Every rainbow parallel, every Prizm, every Optic Shock, every serialized 1-of-1 insert of the last three decades runs on the mechanic Finest introduced.

Between SP and Finest, 1993 finished what 1990's holograms and 1992's die-cuts had started. The base card was no longer the product. The chase mechanic was the product. The base cards were what came with it.

Why the JW50 stops here

The mass-production era is the subject: cards that became iconic because they were everywhere. That is a specific economic and cultural condition. It requires the base card to be the product, distributed at uniform pull rates, priced at commodity retail, and traded on the image and the moment rather than on manufactured scarcity. That condition ended somewhere between the Beam Team in 1992 and Finest in 1993. Everything after runs on a different set of incentives.

This does not mean the inserts don't matter. It means they belong to a different collection. The Cosmic Spider-Man MH5 and the Lombardi Trophy hologram are in the JW50 because they were pulled by ordinary kids from ordinary packs and became iconic images despite the seeded scarcity, but they sit on the edge of the ranked list. The Reggie AU1, the Beam Team Jordan, the SP Jeter, the Finest Griffey Refractor, and the entire modern chase economy that descends from them, sit on the other side of the line. Documenting the exact moment the mechanic changed is how the JW50 knows where its boundary sits.
