Is Your 1966 Washington Quarter Worth $20,000,000? Find the Rare Error You Need to See

A Coin with a Hidden Secret

The Washington Quarter, first minted in 1932 to honor George Washington, is a familiar sight in American change. But some quarters from 1966 are grabbing attention for their jaw-dropping value—up to $20 million! These coins, with Washington’s face on one side and an eagle on the other, were mostly made with copper and nickel. However, a few rare ones from that year have unique errors that make them worth a fortune. Could one be hiding in your pocket right now?

What Makes This Quarter So Special?

Most 1966 Washington Quarters are worth just 25 cents, but a few stand out because of rare minting mistakes. One key error is the “doubled die” variety, where the design—especially the letters or date—appears doubled due to a minting error. Another rare find is a 1966 quarter struck on a silver planchet, a leftover from earlier years when quarters were made with 90% silver. These errors, combined with pristine condition, can push a coin’s value to $20 million at auction.

Error Type Estimated Value Key Feature
Doubled Die Up to $20 million Doubled letters or date
Silver Planchet Up to $15 million Struck on 90% silver

Could You Have a Treasure?

Here’s the exciting part: a $20 million 1966 Washington Quarter might be in your wallet or change jar. Since these quarters were made for everyday use, many are still in circulation. Look for coins with a shiny, silver-like finish or unusual doubling in the design, especially around the words “LIBERTY” or the date. A magnifying glass can help spot these errors. If you find a quarter that looks different, take it to a coin dealer for a professional check—it could be a life-changer.

Stories of Big Coin Finds

People have found valuable Washington Quarters before, sparking dreams of striking it rich. A 1965 silver quarter, similar to the rare 1966 variety, sold for $12,500 at auction a few years ago. Another doubled die quarter from the 1960s fetched $10,000. These stories keep folks searching through their change, hoping for a big payday. With coin collecting growing in popularity, especially as the U.S. nears its 250th anniversary in 2026, these quarters are more valuable than ever.
