1971 Great Britain ½ Pence Two Headed & Two Tailed Set
NGC MS 61 UNIQUE

Great Britain changed to the decimal coinage in 1971, which was the first year that they stuck the new ½ Pence KM-914. Recently, these three unique and exotic mint errors were discovered in an estate of a Mint Superintendant. All three of these coins were struck from the dies used for this new decimal ½ Pence in 1971. These were certified by NGC and are now being offered for sale. One was struck from two reverse dies, another struck from two obverse dies and the third is an unbelievable coin struck by two obverse dies in a different metal. Hopefully these three unique and historic mint errors will remain intact since they belong together.

Chile 10 Pesos Double Struck on Feeder Finger

This unbelievable Mint Error was the feature story for the first issue of Mint Error News Magazine. It is a 1998 Chile 10 Pesos double struck on the actual feeder finger!! This is one of the most incredible and spectacular Major Mint Errors that has ever surfaced.

Canadian 1978 Cent Multi Struck Over 1974 $10 Olympic Commemorative

This is an incredible and unique Canadian mint error. 1978 Cent Dies were struck multiple times over an Olympic 1976 Commemorative $10 that was dated 1974. Although many dramatic and unusual Canadian errors surfaced during the 1970’s, this is the most dramatic and spectacular piece that I have ever seen.

1980 Canadian "Two Tailed" Cent
PCGS MS 64 Red

There are approximately thirty genuine two-headed or two-tailed coins that have been authenticated by PCGS or NGC. There are only four known "Two Tailed" U.S. coins: three Quarters and one Dime. One of the Quarters recently sold for $80,000.

I have handled most of the world coins that were struck with either two obverse or two reverse dies. Two of these are Canadian Copper Cents that were struck with two reverse dies and authenticated by PCGS. I purchased these in a Canadian Mint Error Collection and they have since been featured in a front page Coin World article.

This coin is one of the two known Canadian Copper "Two Tailed" Cents. It was struck with two reverse dies.
