The Roosevelt dime was first struck on January 19, 1946, at the Philadelphia Mint.
It was released into circulation on January 30, which would have been President Roosevelt's 64th birthday.
The planned release date had been February 5; it was moved up to coincide with the anniversary.
With its debut, Sinnock became the first chief engraver to be credited with the design of a new circulating U.S. coin since those designed by Charles E. Barber were first issued in 1892.
The release of the coins was a newsworthy event, and demand for the new design remained strong, although many of Roosevelt's opponents, particularly Republicans, were outraged.
There were reports of the new dime being rejected in vending machines, but no changes to the coin were made.
The dime's design has not changed much in its over seventy years of production, the most significant alterations being minor changes to Roosevelt's hair and the shifting of the mint mark from reverse to obverse in the 1960s.

At the time the dimes were released, relations with the USSR were deteriorating, and Sinnock's initials, JS, were deemed by some to refer to Soviet dictator Joseph Stalin, placed there by a communist sympathizer.
Once these rumors reached Congress, the Mint sent out press releases debunking this myth.
Despite the Mint's denial, there were rumors into the 1950s that there had been a secret deal at the Yalta Conference to honor Stalin on a U.S. coin.
The controversy was given fresh life in 1948 with the posthumous release of Sinnock's Franklin half dollar, which bears his initials JRS.

Although usually more coins were struck at Philadelphia than at the other mints during the years the coin was struck in silver, only 12,450,181 were struck there in 1955, fewer than at the Denver Mint or at San Francisco.
This was due to a sagging economy and a lackluster demand for coins that caused the Mint to announce in January that the San Francisco Mint would be shuttered at the end of the year.
The 1955 dimes from the three facilities are the lowest mintages by date and mint mark among circulating coins in the series, but are not rare, as collectors stored them away in rolls of 50.

With the Coinage Act of 1965, the Mint transitioned to striking clad coins, made from a sandwich of copper nickel around a core of pure copper.
There are no mint marks on coins dated from 1965 to 1967, as the Mint made efforts to discourage the hoarding that it blamed for the coin shortages that had preceded the 1965 act.
The Mint modified the master hub only slightly when it began clad coinage, but starting in 1981, made minor changes that lowered the coin's relief considerably, leading to a flatter look to Roosevelt's profile.
This was done so that coinage dies would last longer.
Mint marks resumed in 1968 at Denver and for proof coins at San Francisco.
Although the California facility beginning in 1965 occasionally struck dimes for commerce, those bore no mint marks and are indistinguishable from ones minted at Philadelphia.
The only dimes to bear the "S" mint mark for San Francisco since 1968 have been proof coins, resuming a series coined from 1946 to 1964 without mint mark at Philadelphia.
Starting in 1992, silver dimes with the pre-1965 composition were struck at San Francisco for inclusion in annual proof sets featuring silver coins.
Beginning in 2019, these silver dimes are struck in .999 silver, rather than .900, which the Mint no longer uses.

In 1980, the Philadelphia Mint began using a mint mark "P" on dimes.
Dimes had been struck intermittently during the 1970s and 1980s at the West Point Mint, in Roosevelt's home state of New York, to meet demand, but none bore a "W" mint mark.
This changed in 1996, when dimes were struck there for the 50th anniversary of the Roosevelt design.
Just under a million and a half clad 1996-W dimes were minted; these were not released to circulation, but were included in the year's mint set for collectors.
In 2015, silver dimes were struck at West Point for inclusion in a special set of coins for the March of Dimes, including a dime struck at Philadel
