There was something oddly welcoming about those old pocket books that feels absent from today’s mass market paperbacks...

Would you agree that there is a difference between not doing something and not being responsible for it?

These are four silver chess pieces from an innovative silver mint in Korea. I quite love the designs . . .

I’m a big fan of the Strike television show (I mean, Tom Burke and Holliday Grainger? I’d watch them reading out the phone book – all the while wondering if they’ll ever kiss). The books make for fun beach reading, full with the never-ending “will they/won’t they”

This unusual silver piece displays four famous pirates and contains an actual working compass. I really think more coins should contain working compasses....

🗡️ Fun sword fact: The word “sword” comes from Old English sweord — but the earliest swords weren’t steel! Around 1600 BCE they were bronze, short, ornate, and bent mid-battle. ⚔️

Fun (and slightly mischievous) castle fact! 🏰💩
Medieval castles had “garderobes” — toilets that emptied straight into the moat. Knights even hung their clothes there, thinking the smell kept moths away. Fashion meets sanitation!

Another beautiful silver “stacker” from the South Korea Mint. It’s easy to imagine the right combination of magic words bringing this sword to life . . .

The earliest tarot cards weren’t mystical at all—they were actually used as playing cards in 15th-century Italy, in a game called tarocchi. It wasn’t until a few hundred years later that people started using them for fortune-telling and divination.

Strange to think that this copper round is entirely modern. It’s beautifully made and makes me wish regular currency could be this dramatic.

In some castles, nobles kept pet lions, leopards, and even polar bears as status symbols. The Tower of London had a whole royal menagerie—there’s even a record of a polar bear in the 13th century that went fishing in the Thames on a long chain!
