🪧 Is it true a famous plate was a fake?

Can a joke fool grown-up experts for forty whole years? This one did! Our story starts at Drakes Bay, on the California coast. In 1579, long before there were any cities here, a sailor named Francis Drake stopped his wooden ship in this bay. People said he left a brass plate there. That's a flat piece of shiny metal with words on it. But nobody ever found it.

Then, when your great-grandparents were little, a club of friends who loved history had an idea. Can you guess it? They made their own plate as a joke, with old-fashioned words on it! They wanted to see if history experts would fall for it. In 1936, the plate was found, and people sure did fall for it. An early metal study said it was real! The club tried to explain it was a prank, but the joke got way too big.

Then, in the late 1970s, scientists tested the plate in lots of ways, the way you might check a toy to see if it's brand new. The plate failed the tests. It was modern, not old at all. It had fooled people for about forty years! Today the plate rests in a college library in Berkeley. It reminds us to ask, is that really true?

On this drive through Canada, let's travel far down the coast to California for a mystery. It's about Drake's Plate of Brass, a metal sign people believed the English explorer Sir Francis Drake left behind. So how does a fake fool smart grown-ups for forty years? In 1579, Drake's ship stopped on the California coast, and a man on board named Francis Fletcher wrote that the crew nailed a brass plate to a post, claiming the land for the Queen of England. Nobody ever found it. Then, in 1936, a battered brass plate turned up near San Francisco Bay, with Drake's name scratched on it.

Historians were thrilled! Some doubted the odd spelling and wording, but an early study of the metal said it was genuine, so most people believed it. Here's the secret. The plate was made by members of a joking club of history fans called E Clampus Vitus, as a practical joke. They even tried to hint the truth to the finders, but the joke had already grown too big to stop. Imagine pranking your friend, and then your friend's prank lands in a museum.

Finally, in the late 1970s, scientists ran a whole list of physical and chemical tests, like a detective checking fingerprints. The metal was too smooth and too modern for sixteenth-century sailors, so the plate failed. Guess how the pranksters felt reading the news! Today the famous fake rests in the Bancroft Library at UC Berkeley. It's still treasured, now as a reminder that even experts should keep asking questions.
