Hi
ATG tetsValuation generally is usually based on
quality and wear of the coin in question and other factors such as whether it is lifetime (333-323BC) or postumous and the
rarity of the
mint (Macedonian issues were the most numerous,
Egyptian and some other disparate mints less so). Oddities of engraving (something added/deleted/some script etc) within a
type (though maybe would make a new
type?) would boost novelty value and beg questions of the coin and its history/circumstances - thus its interest to a collector.
For versions of the same
type (
Price 78 in this case) not likely to be much difference except the condition and the
quality of execution. Different engravers may have cut the same
types which would naturally mean differences in the same
types - the better engraver would attract the better value now, all things being equal.
For the examples shown, these are not particularily well executed though
still in quite
good condition as regards wear.
People will pay a lot of
money for a
rare coin (to finish their
collection) and even more for a spectacularily executed, high in
style coin that finished their
collection!
