James Barton Longacre, the Chief Engraver of the United States Mint, designed this unique reverse for the $20 Double Eagle.
As a result, only a small number of 1861 Double Eagles with the Paquet Reverse were minted, making them highly sought after by collectors.
The Paquet Reverse is recognized for having taller and more slender stars compared to the regular design.
If you possess an 1861 Coronet Head Gold $20 Double Eagle with the Paquet Reverse, it is considered a rare and valuable numismatic specimen.
As always, it's recommended to consult with numismatic experts or professional grading services to authenticate and appraise the coin's condition and rarity accurately.
