The State Quarters program (1999-2008) drove some of the largest mintages in history and pulled an estimated 140 million Americans into checking their change.
The clad quarter is the workhorse of US commerce, and since 1999 the Mint's marketing canvas: State Quarters, America the Beautiful, American Women. For collectors it is the great gateway drug; for stackers it is 9 cents of copper-nickel dressed as 25.
The State Quarters program generated an estimated $3 billion in seigniorage — coins bought and never spent.
Check these before treating any coin as melt. Think you have one? Check recent auction records before selling, and read the grading basics first.
Never clean a coin. Ever. Cleaning permanently destroys collector value — dark original toning is worth more than shiny damage.
Gear that settles it: an electromagnetic verifier, a calibrated scale and calipers — counterfeit basics.
Circulated ones: face value, with rare exceptions (Wisconsin Extra Leaf, some errors). Uncirculated rolls and silver proofs carry modest premiums.
