The amusement park dime

The 1982-P Roosevelt No P dime touched off a wave of change-scouring when stories started appearing in Ohio and Pennsylvania newspapers about the discovery of odd dimes that did not have a Mint mark.   Since 1980, every circulating coin, except cents, has a Mint mark above the date. These dimes, though, were blank.

The Philadelphia Mint had neglected to place a Mint mark on one or two dies.  Coins with a noticeably strong strike surfaced in Sandusky, Ohio. Many were unknowingly given out in change at the city’s Cedar Point Amusement Park. 

In an article in the Central State Numismatic Society’s journal, The Centinel, Steven Bieda wrote, “In March or April of 1982 the amusement park requested its seasonal allotment of coins through Citizens Bank. The bank ordered the coinage from the Federal Reserve Bank in Cleveland. As it turned out, the vast majority of the 1982 No-Mint Mark dimes were contained in this order.”

Less desirable coins with a weak strike were released in Pittsburgh.

Bieda noted that some think that all the No P dimes were struck from the same set of dies, but that the pressure used to strike the coins was raised during the production cycle, resulting in a sharper strike.

Strong-strike 1982 No P dimes catalog for $300 in Mint State 65 in Coin World’s Coin Values.  Weak-strike coins are not cataloged there, but tend to sell for less than half the value of strong-strike coins.

Less, once again, is more when it comes to numismatics.

Both the "weak strike" and the "strong strike" share the same die markers, proving they were struck by the same die pair. The "strong strike" is much more abundant. I cannot determine whether the strong strike preceded the weak strike, followed the weak strike, or whether both strikes are temporally intermixed. Spontaneous increases and decreases in striking pressure are well-documented in a range of error types. -- Mike Diamond
