Another error coin, up to 24,000 doubled die pennies were released by the Philadelphia Mint in 1955. Many of these ended up in packs of cigarettes in New England vending machines as the price per pack was 23 cents, but the machines could only take quarters so the pennies were added to the packs to even up the price. These circulated coins, which feature the telltale blurred lettering and numbers on the reverse, are worth up $2,000 to each.
