Frequently Asked Questions
Why were arrows placed at the date of 1873 coins?
Under the Coinage Act of February 12, 1873, the US Mint slightly increased the weight of silver dimes, quarters, and half dollars to align them with the metric system (two half dollars equaled exactly 25.0 metric grams). Two arrowheads were placed at the date during 1873 and 1874 to alert the public that the coins contained the new, heavier weight standard.
Why was the Coinage Act of 1873 called the 'Crime of '73'?
Because the act quietly omitted the standard 412.5-grain silver dollar from the list of authorized legal coins, effectively putting the United States on the gold standard and demonetizing silver. When vast silver deposits were discovered in Nevada's Comstock Lode, western miners and farmers denounced the law as a conspiracy by eastern bankers, dubbing it 'The Crime of 1873'.
What is the difference between 'Open 3' and 'Closed 3' in 1873?
Early 1873 dies had a numeral '3' with closely spaced knobs that Chief Coiner A. Loudon Snowden complained looked too much like an '8'. Chief Engraver William Barber modified the punch to widen the spacing between the knobs, creating the 'Open 3' variety. Both Open 3 and Closed 3 exist with and without arrows.
What replaced the silver dollar in 1873?
The standard Seated Liberty Dollar was replaced by the 420-grain Trade Dollar, created specifically for export to China and East Asia to compete against the Mexican 8 Reales silver peso.
Which 1873 branch mint coins are the rarest?
Coins struck at the Carson City Mint ('CC') in 1873 are legendary rarities. The 1873-CC Without Arrows Dime is unique (only one specimen is known, which sold for $1.84 million), and the 1873-CC Without Arrows Quarter is also a six-figure mega-rarity.
How can I detect fake arrows on an 1873 coin?
Counterfeiters often solder silver arrowheads onto a cheaper 1873 No Arrows coin, or alter the date of an 1874 With Arrows coin. Microscopic inspection reveals solder discoloration, incorrect arrowhead spacing, or altered tool marks on the final digit.
How much is an 1873 Seated Liberty coin worth?
A common 1873 With Arrows half dollar in circulated Good-4 condition is worth $35 to $50. In Choice About Uncirculated condition, it sells for $350 to $650. In Gem Mint State MS-65, it commands $14,000 to $22,000. Rare Carson City varieties bring $25,000 to over $1,000,000.
