So far, I have found one off-center reverse from the Tang Dynasty and thirty six from the Northern Song Dynasty. The ones in my book range from (I'm guessing) 20% off center and worse. There is one where the square on the reverse almost touches the edge of the coin.Do these actually count as error coins? I have seen them sold at a premium. New question: There are also twenty or more coins in which the center hole was not filed accurately. All are from the Northern Song Dynasty. Some of the file marks are 45º off. Are these especially collectible? There are three coins, all Tao Kuang (1821-1850), with flash which was not filed off the outside edge of the coin. One of these was not filed at all; the other two left partially unfiled. I am assuming these count as error coins. And another: Y.K.Leung refers to "Never-in-ground" coins which have worn so thin that there are actually holes worn through them. Can anyone here write "Never-in-ground" in Chinese? Any information here would be greatly appreciated. If you have the time, I would also like to know the names of all of the trees and other plants on earth and the names of all of the stars in the sky, but that can wait for a while.
"Error" coins in ancient numismatics is not really the same as modern. In modern coinage, "mostly" perfection is the norm, so errors are rare. In ancients, in many issues, "errors" or poor coining is the norm. Most Chinese errors such as offstruck, edge not filed, etc are not worth a premium, actually worth less than normal. There are what are called "rosette" holes in Chinese coins. This is when the rod poked into the center hole to hold the coins goes in not square but at a severe angle, effectively making an 8 pointed star. These rosettes sometimes have a slight premium, but really only if the square is now 8 sided, not just slightly off. Btw, anyone else having this weird error here where the screen is like 5 foot wide?
