MAR10 Day 2026 is not just another branded hashtag. Super Mario Bros. turns 40 this year. The Super Mario Galaxy Movie hits theaters April 1. Nintendo is throwing everything at this one.
eShop sales running up to 90% off. Physical game deals at every major retailer. A GameStop world record attempt. New amiibo. A $180 LEGO kart. A Lunchables partnership giving away Switch 2 consoles. And sealed Mario games are still pulling five and six figures at auction.
Here's what matters if you collect anything with a mustache and a red hat.

The Collectibles Pipeline
Two extra-large Super Mario Galaxy amiibo launch April 3. Mario flying through a launch star and Rosalina with Lumas. $39.99 each. Timed to the movie release.
Before those hit, three more amiibo drop March 26: Elephant Mario, Captain Toad with Talking Flower, and Poplin with Prince Florian.
LEGO is launching the 72050 Mario Kart Luigi and Mach 8 Kart on April 1. It's an 18+ set at $179.99. Companion to the 2025 Mario and Standard Kart set that was 1,972 pieces at $170. These are display-grade builds for adult collectors.
Sealed Mario Games Still Command Serious Money
A sealed Super Mario Bros. (NES, 1985) holds the all-time record for any video game sold at auction. $2 million. Rally, 2021.
Two weeks ago, a sealed Super Mario Bros. WATA 8.0 sold for $26,108 at Goldin's Pop Culture Elite auction. Not a gem mint copy. An 8.0. And it still pulled five figures.
A sealed 1989 NES Super Mario Bros. CGC 9.8 went for $57,340 in the same window.
The retro gaming collectibles market crossed $4 billion in 2026 and is projected to hit $8.5 billion by 2033. Mario is the single most recognizable character in the medium. Every anniversary, every movie, every cultural moment sends attention back to the original games. And attention drives price action.
The Galaxy Movie Effect
The Super Mario Galaxy Movie opens April 1. Chris Pratt returns as Mario. Brie Larson joins as Rosalina. Jack Black is back as Bowser. It's projected to open above $150 million.
The first Mario movie in 2023 did $1.36 billion worldwide. If the sequel performs anywhere near that level, every Mario collectible gets another wave of mainstream attention.
That includes the sealed games, the amiibo, the LEGO sets, and anything vintage with a Mario logo on it. Movie tie-in collectibles don't always hold long-term value. But the underlying catalog of vintage Mario items benefits every time the character trends.
Nerdworth Is Running a Mario Day Auction
Over on Nerdworth, ACEO artists are putting up Mario-themed original art cards for the occasion. Hand-painted, one-of-one pieces in the 2.5 x 3.5 format. It's the kind of crossover between art collecting and gaming culture that the ACEO format was built for.

The Bottom Line
Mario turned 40 and Nintendo is treating it like a full-scale campaign. The eShop sale, the GameStop world record attempt, the movie in three weeks, new amiibo, a $180 LEGO kart, and a Lunchables tie-in that might put a Switch 2 in your kid's lunch box.
If you own anything Mario, this is the year it gets attention. If you're starting a collection, the game deals have never been cheaper and the vintage market keeps proving that sealed Mario inventory only gets more expensive with time.
The plumber is 40. He's not slowing down.
