With a mintage of 345,570,000 pieces, the 1970 Roosevelt Dime (#85137) arrived four years after the U.S. Mint ceased production of 90% silver dimes (last dated 1964, but struck through 1966). While this figure would have been staggering during the silver era, it actually represented a significant dip compared to the billion-coin mintages seen during the mid-60s "date freeze."
The year 1970 was the first full year under Mint Director Mary T. Brooks, who took office in late 1969. It was a period of logistical shifts; the Philadelphia Mint was transitioning between its third and fourth facilities, and the cooling economy had lowered the overall demand for new coinage.
The Mint was also experimenting with technology. While standard presses struck two to four dimes per stroke, a high-speed "Superpress" developed with General Motors, intended to strike 144 coins per revolution, failed to meet expectations and was shelved. Additionally, the Mint was still outsourcing its clad strip production, a process it wouldn't bring in-house until 1972.
By 1970, Gresham’s Law, which is the economic tendency for "bad money" to drive "good money" out of circulation, had largely taken effect. Most silver coinage had been hoarded by speculators or reclaimed by the Treasury Department. While silver dimes still appeared occasionally in change, the copper-nickel clad version had become the undisputed standard. The Mint's massive production of clad coins would have drowned out the remaining silver "tenor" regardless.
Today, after more than 50 years in circulation, 1970 Roosevelt Dimes still turn up occasionally in pocket change. However, most are heavily worn (VF grade or lower) and hold no premium over their 10-cent face value.
The market for uncirculated 1970 dimes is trifurcated based on condition and certification:
Circulation-strike dimes from Philadelphia do not bear a mintmark. Beginners often confuse these common coins with the rare 1970 "No S" Proof Dime, a famous error where the San Francisco "S" mint mark was omitted from a Proof die. Unless your dime features the mirror-like surfaces and sharp relief of a Proof strike, and was originally issued within a 1970 Proof Set, the absence of a mintmark simply indicates it was struck at the Philadelphia Mint
