This is probably the most extreme example I have seen. Unlike other date doubling from 1940 10c coins I have seen, this date either was hub-doubled or repunched. This example is more extreme than those Hans Zoell documented. Zoell originally called this 261F in 1961, with a die crack through 10 CENTS. Then, he decided to call this coin part of the north offset of progressive date doubling and catalogued it as R262e in 1965. This is where Zoell classifications can get messy, because this coin is more like the 261F example, with die cracks, than the progessive Die Deterioration Doubling of R262e... Anyhow, this is a tough coin to find, this recently found example is VF-30.

SPP...I have never seen a coin doubled and offset that much as your coin is....Did you find it in your pocket change...?
Very, very nice find.

Is there any other evidence of doubling on the sails or elsewhere on the reverse?... I can't really see from the date that this is purely hub doubling as there appears to be doubling in different directions on the date digits.

Can you post a pic of the whole reverse please?

PG, the 10 CENTS is doubled, but not as much. The rest of the reverse devices are not doubled, I wonder if this is a repunched date (the RCM also did some wonky things with the date on the NFLD 1c and 10c coins struck in 1940 as well...). This is certainly not MDD, because the denticles adjacent to the date are pristine and not doubled at all.

I think the incompleteness of the numerals on your coin adds to the dramatic effect,other coins have similar offset.Not MDD,not likely a repunched date to extend die life like the newfoundland coins.

It appears to me that there are some aspects of tilted hub doubling as the date is the main subject of doubling... it also appears that the working hub rotated when leaving the working die because it looks like directly below the 4 and 9 that the metal has been pushed up. Not too sure about the repunch aspect as the last punch is usually clean and the doubling appears around that clean image.

Some speculation
It's 1940,first year of the war,the demand for coins is such that the mint must produce more than double the coins of any previous year.Some skilled mint workers have gone to war and skilled manufacturing workers are hard to come by with the country gearing up for wartime production.The pressure to produce is on at the mint.One or more dies is first sunk with a hub on which the date has deteriorated,then with a different hub.

Almost as much offset on mine. No other doubling. Faint die clash of sail in front of king's face.  |

The Terry-T coin was struck earlier in the life of the working die ... it looks like SPP's coin was struck later and the 9 and 4 digit details are starting to deteriorate with usage.... a puzzling point though, the doubled image of the 9 seems to be moving down if you look inside the closed loop of the 9.

Nice examples of Die Deterioration Doubling(the life of). Remember the mint kept pushing dies to the limit in this era. |

I picked up the following at yesterday's coin show in Cambridge.   Forgive the picture quality as all I have is a scanner. It is an earlier die state of SPP's coin (complete with die cracks through the 10 cents). Looking at the images, Terry-T's coin, although similar, looks like it has been struck from a different die. If you look at the doubled image inside the 9, it is offset to the right on the SPP coin and to the left on the Terry-T coin.... It was fun looking into the 10-cent area (rather then the 50ct which I normally look at) although you need a good/younger set of eyes for the smaller details. |
