1965

The 1965 Roosevelt dime is the first clad dime in American history and the highest-mintage dime ever struck up to that point, with Philadelphia producing 1,652,140,570 pieces during a year of unprecedented coin-shortage pressure. The Coinage Act of July 23, 1965 eliminated silver from the dime and quarter in response to the silver-hoarding crisis that had emptied bank tills and vending machines, replacing the 90% silver alloy with a copper-nickel sandwich. The Treasury further directed that no mintmark appear on any 1965-dated coin, regardless of which mint actually produced it, to discourage hoarding by date-and-mint collectors and to allow all three mints (Philadelphia, Denver, and San Francisco) to share production of the dated coinage without distinction. The calendar-year freeze policy meant some 1965-dated dimes were actually struck into 1966, and the reported 1.65-billion figure represents the entire dated output rather than work performed within the calendar year.

The 1965 follows the new clad specifications: 2.268 grams, 17.91 millimeters, outer layers of 75% copper and 25% nickel bonded to a pure copper core, reeded edge, with a coin composition by mass of roughly 91.67% Cu and 8.33% Ni. Sinnock's 1946 design carries over unchanged from the silver era, with the FDR portrait on the obverse and the torch with olive and oak branches on the reverse. Authentication centers on confirming a clad coin rather than a silver one: a 1965 weighs 2.268 grams against the silver 1964's 2.5 grams, and the edge of a worn coin shows the distinctive copper stripe running between the two cupronickel cladding layers. Strike quality through the first year of clad production was inconsistent because mint operators were still calibrating press tonnage and die life against the harder cupronickel planchet, and weak FB (Full Bands) torch detail is common on bag-handled survivors.

Survivor distribution skews heavily toward circulated and low Mint State grades because the mintage was so vast that hoarding pressure on the new clad coinage never developed the way it had on the late silver issues. MS65 and MS66 examples are plentiful, but MS67 and MS67 FB pieces are condition rarities because roll handling, bag marks, and weak strikes from the transitional press setup limited the supply of high-grade survivors.
