Ummm, "Double Die" and not Doubled Die? Ummm... That's one heck of a Type-O!

It was originally published in French.
A lot doesn't make sense due to poor translation.
In the French version it is correctly called doubled die not double die.
Retarded coin should have been slow ejection = double struck or indent due to ejection problem

The coin in this thread would be classified by them as retarded coin http://goccf.com/t/406903&SearchTerms=indent

Hans Zoell classified the following items as varieties and anything else was an error. It is a coin struck with an approved design, on good planchets, with good approved dies, and with good calibrated equipment using the proper pressures/force. Zoell never classified an MD as a variety .. it was an error. Most of those he thought should be errors were published in the pamphlets titled "Minor" in the name. For varieties , you need to get the "major" pamphlets/guides. He split the minor anomalies after the 3rd edition .... from 1 to 3, you could fing both errors and varieties in the pamphlet.
