I Asked ChatGPT What the Most Expensive Coins I Could Find in My Pocket Are

Many people dream about finding a coin worth a billion dollars in an old coat pocket, but I have a more modest wish.

Struck accidentally on leftover bronze planchets during a year when pennies were supposed to be steel, authenticated examples of this error have sold for well over $100,000. It remains one of the most talked-about "check your change" coins for exactly that reason.

Visible doubling in the date and lettering makes this one identifiable without special equipment. Circulated examples can be worth over $1,000, with pristine ones reaching considerably higher.

A subtle variation in the size of the date on some 1970-S pennies makes this one worth real money to collectors who know the difference, though it requires closer comparison than most of the coins on this list to identify correctly.

Dimes, quarters and half dollars dated 1964 or earlier are 90% silver, and even the most common dates are worth several times face value purely on metal content, before any collector premium gets added on top.

Low original mintage makes both dates worth a real premium even in heavily worn condition, with better-preserved examples reaching into the thousands.

Many circulated examples have worn dates, but ones with a fully legible date from these earlier years can carry a meaningful premium over a common, later-date Buffalo nickel.
