Error coins always create a stir among coin collectors. In 1983, dimes without mintmarks began to emerge in circulation. Numismatic News had the story.

No-mint-mark 1982 dime discovered

By Alan Herbert “News” Columnist

The first know circulation strike U.S. coin that can be proved to be from a die that is supposed to have a mint mark has been discovered by an Ohio News reader.

Walter Placzankis spotted the coin in December and forwarded it to us for authentication. Detailed examination of the coin shows normal flow lines in the planchet metal in the area where the mint mark should be. This confirms that the die was placed in service without having a mint mark punched into it.

The coin is a 1982 dime in nearly uncirculated condition. The automatic assumption is that it is from Philadelphia which only began using mint marks on a regular basis in 1980 on all coins except the cent.

However, this could be a Denver product, so unless the Mint is able to trace the die or has a record of its being spotted and removed from service, it will probably never be know which of the two mints struck this coin and undoubtedly others before the die was removed from service. Mint officials said after a preliminary check of die records at both Philadelphia and Denver that they has no record of such a die.

A circulation strike coin (other than the cent) without a mint mark has been a variety that would be impossible to confirm up until 1980, because if a die without a mint mark has been used at either Denver or San Francisco (for other than a proof coin) it could always be considered a Philadelphia strike, but now that Philadelphia is using a mint mark, that escape door has been closed.

While it is possible that as many as 750,000 to 1 million coins were struck by this particular die, it appears doubtful at this point that the die was used for its full production life.

We have placed as $50 price tag on the discovery coin as a temporary quotation until we can determine actual mintage figures or until sufficient quantities turn up to enable us to estimate the mintage.
