The 1794 Flowing Hair Dollar with rare silver plug variety is believed by some experts to be the very first official US Dollar ever minted.
1794 marked only the second year of operations after the US Mint first opened its doors.
Some overweight planchets had internal silver plugs inserted to reduce mass to proper standards.
Survived over 225 years in exceptional condition. Recently sold at auction for over $10 million.
Matching die state as trial pieces, sharp initial strike, and perfect alignment indicate first coin status.
In contrast, all other 1794 dollars show some degree of die clashing, misalignments, etc pointing to later strikes.
As perhaps the genesis strike of US federal coinage, this piece holds an unmatched pedigree.
