The Parthian is more attractive to me than if it were perfectly centered. Moreover, the reverse favors the legend of the bottom losing most of the two lines at the top. Few of these coins will show all the lines of this complex legend. This was a truly fortunate coin. Centering is very much a matter for individual opinion.
Some collectors greatly value coins that show full legends and design.
Others will accept the loss of peripheral items as long as there is a nice portrait on the flan. We each must decide where we stand on this matter and buy coins that strike us as appropriate. Late 5th century BC Two similar silver staters from the same town offer a choice of type. This is not a mint error but a numismatic fad that was observed by several cities in the region. A few years later the same city issued coins with the same city symbol, the tripod, but with a very pleasant type of an eagle perched on the head of a deer.
