One box, three cards, not a single base card. Everything signed, everything on metal stock. The inaugural edition of a series that puts boxing, MMA and wrestling on one checklist.

Let us say it straight away, because it is everyone's first reaction: this box holds three cards. Not three packs, not thirty cards. Three.

And that is precisely the point. Leaf Metal Ring Kings does away with the base card entirely. There is nothing to sort, nothing to set aside. All 101 cards on the checklist are autographed, all on metal stock, all numbered to short print runs. Each box yields 3 certified autographs on average. The hit rate is one hundred per cent, which shifts the question completely: you no longer wonder whether you will pull something, but who.

A checklist spanning three disciplines

This is the inaugural edition, and Leaf thought big. The series gathers boxers, MMA fighters and wrestling figures onto a single list, which is rare: these worlds seldom meet in trading cards.

On the boxing side you will find signatures from Mike Tyson, Floyd Mayweather Jr., Manny Pacquiao, Julio César Chávez, Oscar De La Hoya, Sugar Ray Leonard, Tyson Fury and Ryan Garcia. In MMA, Jon Jones. In wrestling, Bret Hart and Steve Austin are among the signers.

The subsets to chase

Knockout Kings, a die-cut set reserved for fighters who have put opponents on the canvas.

Title Belt, also die-cut, its checklist limited to those who have won at least one belt.

Shadow Boxing, built on two layers of acetate to create a genuine shadow-box effect around the signature. Visually the most striking of the series.

Fighting Machines, devoted to those whose stamina seemed bottomless, alongside the Inscriptions and Illustrations subsets.

Uppercuts, cut signatures from departed boxing legends: George Foreman, Jack Dempsey, Joe Louis, Muhammad Ali, Rocky Marciano, Sugar Ray Robinson. And Wrestling Kings, its counterpart for the major wrestling figures of the seventies and eighties.

Feud and The Fight, two dual-signature subsets. The first pairs wrestling rivalries, the second boxing and MMA bouts that stayed in the memory: Mayweather against Pacquiao, Chávez against De La Hoya, Fury against Wilder, Jon Jones against Daniel Cormier.

What plays out at case level

Two guarantees apply not to the box but to the full ten-box case: 1 to 2 multi-signed cards per case, and 1 on-card autograph from the Kickboxer subset, featuring Jean-Claude Van Damme, Michel Qissi, or a dual signature from both actors of the 1989 film.

In other words, these cards can turn up in a single box, but nothing guarantees it. We would rather write that plainly than let anyone assume otherwise.

Who this product is for

Not for anyone trying to complete a set: at three cards per box, it is the wrong tool. It is for anyone after a signed piece who accepts the premise: few cards, but every one of them a certified autograph on a limited print run.

Brand new, factory sealed, shipped from Switzerland. Contents are random: any guarantees announced by the manufacturer apply to the box, or to the full case depending on the case, never to a specific card.
