Unusual Items: Remarkable Double Denomination Mule 1993-D Cent with Dime Reverse

ha_11c_error_fun09U.S. coins struck with dies of different denominations are extremely rare. Until recent years, none were known.

The most famous among those are the Sacagawea dollar reverse, paired with a statehood quarter obverse, of which ten examples are known, per Fred Weinberg.

In Heritage’s April 2006 Central States Signature, a 1999 cent with a dime reverse hammered down for $138,000, the largest prices realized for an error coin in a Heritage auction, excluding the 1944-S steel cent that sold for $373,750 in our 2008 ANA Signature.

Aside from malfeasance of a mint worker, the muled denomination error is only possible when the denominations involved are similar in diameter. A cent is 19 mm, and a dime is 17.9 mm, a difference of 1.1 mm or approximately 5%.

Given the billions of cents struck annually at the Federal mints, it was inevitable that an absent-minded worker would pair cent and dime dies.

Presumably, the mistake was discovered and the struck pieces were destroyed before dispersal, with the single exception of the present survivor.

This lustrous Gem shows the characteristics expected of a cent and dime mule. The dime side has a broad, tall rim, since metal was forced into the collar of the dime die by the wider diameter cent die opposite. As a result, the cent side has a soft strike near the rim, since metal in the vicinity flowed into the dime collar.

This coin is being offered for sale at Heritage’s 2010 FUN Auction as Lot 2383

    I love the mule coins, and just beginning to appreciate how rare they and how interesting a coin they are. I wish i had one, i would like to offer a NEW FIND and ask if anyone has ever found a IKE MS 40ty % silver doulbed die coin, being struck with a OBV and REV PROOF DIE, the MS IKE coins are exactly like the PF IKE COINS, same weight – same dimensions – same silver content, but the MS planchets are struck with a MS dies and PROOF planchets are struck with proof dies, TO THE POINT– i just got back from ANACS my IKE dollar and is a MS 66 IKE DOLLAR that PROOF Dies were used. Would you call this a PRESENTATION PEAICE? I thought all presentation coins were immediatly melted after being reviewed. When i first bought the coin it was in a lot of blue packs and i thought it look strange, the letters on from and backed looked like proof dies had been used and so i sent it out to ANACS to future ID what was going on with this coin. I also noted there was a finger print on it, slight but a print, and some ground garbage. My therory is that the planchet was on the floor and a worker picked it up and threw it in the proof bucket not thinking i quess, with floor residue and finger print i think this may be a logical explaination. Sorry to be so longe winded, i love reading all your finds and only recently could give you something i thought might interest you- write me and give me your thoughs about this might be a presentation coin- thank you — chuck [email protected]

    Received a cent dime this week from a small convenience store owner in my neighborhood. She knows I have an interest in old and unusual coins. She asked what I knew about this particular coin and I said its interesting but I would have to look into it. She thought it might be a trick coin, but I have looked at it and I don’t think it is. She gave it to me as part of my change. If it has any value I will give her half. Any one out there know where I should send it to have it authenticated?

    Description as follows … Roosevelt dime reverse strike on zinc. Lincoln memorial strike die rotated on bare copper.
