$200 Quarters? Check Your Loot

Double denomination coins, like the $216 Washington quarter, are termed "planchet" mistakes.

The error happens during minting a blank coin (a "planchet").

The U.S. Sun reported that mistakes might arise when the incorrect planchet is placed into the minting press or when the machine mixes up its dies.

If you keep your spare change in a jar, bowl, or piggy bank, you may want to check for valuable coins.

If you don't save extra change, look beneath sofa cushions, under your vehicle, and other places.

First, seek for coins with unique designs, "off" printing, or the incorrect denomination. Double-check.
