Diagon Alley Weasleys’ Wizard Wheezes (76422)
When Fred and George opened Weasleys’ Wizard Wheezes in the heart of Diagon Alley, they weren’t just selling puking pastilles and sticky trainers – they were selling magic with a mischievous grin. And in true LEGO fashion, the 76422 Diagon Alley Weasleys’ Wizard Wheezes set bottled that same energy in brick form.
Released in 2023 and quietly vanishing from shelves in November 2024, this set lived a fleeting but fabulous 17-month lifespan – short even by wizarding owl-post standards. If you blinked, you may have missed it. But as with any good Weasley product, those who grabbed a copy may be in for more than just a laugh.
A shop front brimming with character
At first glance, the build itself is as flamboyant as the twins who ran the store. The oversized, bright orange exterior practically shouts across Diagon Alley. It’s a feast for detail-hungry builders and a perfect slice of the Harry Potter world to display on a shelf.
Minifigures worth their weight in Galleons
The seven minifigures included in the set are nothing short of a collector’s jackpot:
- Fred Weasley (hp433)
- George Weasley (hp435)
- Ron Weasley (hp436)
- Ginny Weasley (hp437)
- Romilda Vane (hp434)
- Lavender Brown (hp432)
- An Owl Post Worker (hp431)
The twins in particular have strong appeal – LEGO Weasleys aren’t as common as you’d think, and their popularity has always soared among Harry Potter fans.
Investment magic: Past, present, and future
Now let’s talk Galleons, Sickles, and Knuts – or in this case, pounds sterling.
Original retail price (2023): around £85
Current new and sealed value (2025): ~£132
Used value (good condition): ~£100
That’s a tidy bit of growth, with sealed sets seeing an impressive 43.3% annual growth since release. Like any good prank, the explosive early growth is expected to fizzle slightly, with forecasts leveling off to a still-solid 11.2% annual growth going forward.
In other words, the set may no longer be hiding a Peruvian Instant Darkness Powder in its box, but it remains one of the more enchanting LEGO Harry Potter investments in recent memory.

The collectors perspective
The allure here isn’t just financial. Although there’s a larger version of this in the 75978 Diagon Alley set this is the only standalone release of the Weasley twins’ shop, and its retirement ensures it will stay unique.
With its short shelf life, playful design, and fan-favorite minifigures, 76422 is destined to become a jewel in many collections. Whether you’re investing for long-term gains or just want to grin every time you walk past your LEGO shelf, Weasleys’ Wizard Wheezes is a set that delivers.
If you have one sealed away in your vault, you might want to hang onto it. And if you don’t? Well, best start saving your Galleons – because this set is no joke when it comes to value.
