Roll With History - Mini Museum + Fanroll Dice

Created by Mini Museum & FanRoll Dice

Dice with Authentic Dinosaur Fossils, Chain Mail, and Meteorite inside!

Latest Updates from Our Project:

We Launch in ONE WEEK ⏳🎲
2 months ago – Tue, Jan 20, 2026 at 08:27:02 AM

We’re officially one week out! 🎉

Roll with History launches in just seven days, and to mark the countdown, we wanted to share a little something with you.

Check out this short video featuring Neil Hoffman (CEO of FanRoll Dice), Jamie Grove (Co-Founder of Mini Museum), and Cassandra Grove (Lead Researcher at Mini Museum), as they discuss this collaboration and how it came together.

In the video, we cover:
  • Why FanRoll and Mini Museum partnered on this project
  • What goes into sourcing and authenticating real specimens
  • How dinosaur fossils, meteorites, and historical artifacts became playable dice
  • The care taken to ensure ethical sourcing and responsible handling
  • What backers can expect when this project launches


This project exists because of the overlap between two worlds: FanRoll’s experience crafting high-quality tabletop components, and Mini Museum’s expertise in sourcing, researching, and documenting real historical and scientific material.

A Quick Reminder Before Launch
If you haven’t already:
  • Following the campaign gets you a free enamel pin when you pledge
  • Reserving your pledge gets you an exclusive mini dice bag designed to help protect your specimens

Both are our way of saying thanks for being here early.
We’re incredibly grateful for the thoughtful discussion you’ve brought to this project so far. In one week, we finally get to put this thing into the world!

Two d20s, 2 VERY Different histories 🎲
2 months ago – Sat, Jan 17, 2026 at 11:38:35 AM

Hey everyone!
We're back with another look at what's coming in Roll with History, and this week we're focusing on two d20s at opposite ends of the timeline.

One comes from the birth of our solar system - the other comes from the final days of medieval armor.

Both are real, authenticated, and ready to be rolled!

🌠 Campo del Cielo Meteorite d20

Formed ~4.5 billion years ago | Fell to Earth ~2500 BCE

Thousands of years ago, a massive metal meteorite broke up over the skies of northern Argentina and rocketed to the ground. The impact was witnessed by local indigenous groups, many of whom lost their lives in the forest fires that followed. Oral histories of indigenous groups tell us that the fall from the sky was witnessed and sparked massive forest fires. The impact area was originally called Piguem Nonralta by the locals, though Spanish colonists renamed it in 1576 CE as Campo del Cielo, or "Field of Heaven."

The Campo del Cielo meteorite is thought to have formed 4.5 billion years ago during the creation of our solar system. With a total recovered weight of 220,562 lbs, it is possibly the heaviest meteorite to have ever been recovered on Earth.

This d20 contains an authentic fragment of the Campo del Cielo meteorite, recovered from Argentina and sourced and authenticated through Mini Museum.

⚔️ Medieval Chain Mail d20

15th Century Central European Hauberk
Valued for flexibility in combat, chain mail was the primary defensive armor in Europe for more than one thousand years. It was flexible and light enough to keep a warrior unencumbered (though not exactly comfortable), but tough enough to fend off blows from enemies. 

Mail armor was made by punching or riveting thousands of metal rings, then weaving them together in tightly interlocking patterns. Entire shirts - called hauberks - were built ring by ring by skilled blacksmiths.

This d20 contains an authentic mail link from a 15th-century Central European hauberk, sourced and authenticated by Mini Museum before being sealed into the die.

Why These Matter
These two d20s couldn’t be more different - one born in space before Earth existed, the other shaped by human hands in the final chapter of medieval warfare.

We're launching Roll with History on January 27! Thanks again for following along!

Revealing the Dino Dice! 🦖
3 months ago – Tue, Jan 13, 2026 at 12:04:32 PM

Hey Everyone!
We are just a few short weeks away from launch, and we'd just like to thank everyone who has followed the project so far. The questions, debates about physics, and strong opinions on dinosaur poop have made this a very fun lead-up!

Roll with History launches on January 27, and we're excited to finally start sharing more of what's inside the project. So let's talk dinosaurs! 🦖

The Full Dinosaur Fossil Dice Set

Up until now, we've only revealed one die from the Dinosaur Fossil Set. It's time to finally share the full lineup!

Each die in this set contains a real dinosaur fossil specimen, sourced and authenticated by Mini Museum. Every piece is tied to a specific species, formation, location, and time period. Here's what's in the full set:

d20 - Tyrannosaurus Rex bone fossil

Hell Creek Formation in South Dakota • ~66 million years old

The king of the dinosaurs! T. rex grew up to 40 feet long, weighed about 9 tons, and had teeth up to 12 inches long. Evidence suggests it both hunted and scavenged to fuel that massive body

d12 - Hadrosaur (Edmontosaurus) bone fossil

Lance Formation, South Dakota • ~66 million years old, Cretaceous Period

Hadrosaurs were large, herd-living herbivores found across the prehistoric world. Some reached nearly 49 feet long and weighed up to 17.5 tons. Their famous "duck bills" were actually bone structures packed with hundreds of small teeth for grinding through tough plant material.

d10 - Alamosaurus bone fossil

Javelina Formation, West Texas  • ~66 million years old

The largest dinosaur every discovered in North America. Alamosaurus stretched up to 85 feet long and weighed over 30 tons. Some fossils were found just feet below the extinction boundary, pleacing it very close to the end of the dinosaurs.

d8 - Stegosaurus plate fossil

Morrison Formation, Colorado • ~150 million years old

Did you know those back plates weren't attached to the skeleton? They actually formed in the skin and were likely used for temperature regulation. Some of the largest plates reached nearly two feet tall.

d6 - Triceratops bone fossil

Hell Creek Formation, South Dakota • ~66 million years old

At 30 feet long and 10 tons, the Triceratops was no pushover. Fossils show evidence of battles with Tyrannosaurids, and their horns and frill likely played roles in defense, mating, and herd recognition.

d4 - Dinosaur coprolite

Morrison Formation, Utah • ~150 million years old
Yes, it's fossilized dinosaur poop. And yes, it's incredibly informative! Coprolites help scientists understand dinosaur diets, movement, and behavior. Also, it makes blaming your bad rolls extremely literal.

d100 - Pachycephalosaurus bone fossil

Hell Creek Formation, South Dakota • ~66 million years old

Known for its thick, domed skull, Pachycephalosaurus likely used its headgear for combat and display. Some fossil domes show stress fractures, suggesting head-butting was very much part of the plan.

Don’t Forget the Follower Gift 🎁
Since you're already following this project, you'll receive a free enamel pin when you pledge. Thank you for being here early!

And if you reserve your pledge for $5 now, you'll also receive an exclusive mini dice bag when you back the project! It's designed to help you protect your specimens once they're in your collection


What's next?
We'll be sharing more updates between now and launch - including more about the other historical materials in the collection and some other fun extras we have planned!

Thanks again for following!
