The 1793 Chain Cent was the very first coin struck inside the new United States Mint in Philadelphia. Chief Coiner Henry Voigt began striking on February 27, 1793, producing a total mintage of 36,103 pieces before public outrage over the 'shackles' of the chain design forced its immediate redesign into the Wreath Cent.
ΔW(%) = [ (Wactual - Wlegal) / Wlegal ] × 100%
Where:
• Wlegal = 208 grains (13.48 grams) under the revised 1793 standards
• Wactual = Measured weight on precision numismatic analytical balance
⇒ Legal Tolerance Band: ± 4 grains (± 1.92%). Planchets outside 200–216 grains were rejected and adjusted by hand filing.
da / dN = C × (ΔK)m
Where the high striking stress on the unhardened early American carbon steel dies caused rapid crack propagation from the forehead of Liberty into the rim after fewer than 6,000 strikes.

Frequently Asked Questions
What is the 1793 Flowing Hair Chain Cent?
The 1793 Chain Cent was the first circulating coin struck by the United States Mint inside its own building in Philadelphia. Authorized under the Coinage Act of 1792 and engraved by Henry Voigt, it began striking on February 27, 1793.
What is the difference between 'AMERI.' and 'AMERICA' varieties?
On the very first die pair (Sheldon-1), Chief Coiner Henry Voigt miscalculated the spacing of the letters around the rim and had to abbreviate the country's name as 'AMERI.'. On subsequent dies (Sheldon-2, 3, and 4), the letters were sized and spaced properly to fit the full word 'AMERICA'.
Why was the chain design controversial in 1793?
The 15 interlocking chain links on the reverse were intended by the Mint to symbolize the unbreakable unity of the 15 United States. However, newspapers and critics immediately attacked the motif, claiming the chain was a symbol of British tyranny and slavery, prompting the Mint to replace it with a laurel wreath after only five weeks of production.
How many 1793 Chain Cents were struck?
A total of 36,103 Chain Cents were struck between late February and late March 1793. Today, numismatists estimate that fewer than 1,000 survive in all conditions combined.
What does the edge of a 1793 Chain Cent look like?
Genuine 1793 Chain Cents feature a decorated edge consisting of alternating vine leaves and bars applied using a Castaing machine before the planchet was struck with the obverse and reverse dies.
How can you authenticate an authentic 1793 Chain Cent?
Authentic specimens feature microscopic diagnostic die cracks (such as the forehead crack on Sheldon-4), specific letter punches used exclusively in early 1793, and planchet weights clustering near the statutory 208 grains (13.48 grams).
What is the highest auction price ever paid for a 1793 Chain Cent?
The auction record is $2,350,000, achieved in January 2015 at Heritage Auctions for the finest-known Sheldon-1 'AMERI.' variety graded PCGS MS-64BN from the Donald G. Partrick collection.
