Here’s one of my die clashed 1857 Flying Eagle Cents. This is a well known and II familiar die clash as the obverse of the Flying Eagle Cents has die clashed lines from a Liberty Seated Half Dollar obverse. Most notable between the head and wing at 9 o’clock and at 3 o’clock is another die clash from Liberty’s seat to the eagles tail feather.
Worth a bunch also in higher grades..... 1857 Flying Eagle Cent. Snow-9, FS-402. Obverse Die Clash with Liberty Seated Half Dollar. MS-64 (NGC). CAC., MS64 - PCGS Auction Prices
