Interesting rarity. This inconceivable error came about thanks to a Mint employee who failed to add the mintmark onto an obverse die. Many experts believe the Weak 1982 No Mintmark dimes were created before the Strong versions. It is very possible that a mint employee noticed the weakly struck examples early in the production process, then increased the striking pressure to obtain a better and stronger strike (resulting in the Strong variety). The die cracks on Clyde's coins may have been the result of the increased pressure. Once this damage was noticed by the press operator, the die would have been pulled and discarded, thus ending the production of 1982 No Mintmark dimes. In 1982, the expected life of a single die pair was 75,000 circulation strikes, placing an upper limit on the mintage of the 1982 No Mintmark dimes. However, if the increased striking pressure caused the dies to crack prematurely, the actual mintage might be significantly lower.
