Before 1933, the US minted a few different kinds of gold coins that collectors really go after today. Among them are the Double Eagle, Half Eagle, and Quarter Eagle. The Double Eagle is pretty special because it's worth $20, making it both the biggest and most valuable one from back then. Then you've got the Half Eagle valued at $5 and the Quarter Eagle at just $2.50; they're not as big but still super popular among folks who collect coins. What makes these gold coins stand out is their rarity and how much history they carry with them since there aren't too many around anymore.
