That is a truly massive hoard. Not only are coins from that hoard flooding the market, but still bringing healthy to mind-boggling prices, coins from other hoards, collections and individual finds are also presenting themselves. Here are three encrusted Owls, recently offered by an Israeli seller. All three came from, I believe, the West Bank and all three are probably imitations. As an iconic type that many ancient collectors are seeking, demand seems very solid, so far.
Nice catch! Yes, at the time of purchase the cost, with the buyer's fee and currency conversion can appear to be too high, but that's a very nice example that might, right now, be more in the $1,000+ category.
Even at just above 700 a couple years ago, that wasn't bad. Even though I'm a type guy, buying only 1 of a type, I've thought about buying more just because they are reasonable. If the hoard truly is more like 30k+, there should be more time to get some nice examples at around the 1000-1200 mark if patient enough.
Nice coin ! I disagree with the attribution as an Eastern imitation. It shares many features of the last coins of Flament group III e.g. i found that his Obv. III.33 / Rev. II.r feets particularily well. The book of Flament "Le monnayage en argent d'Athènes" is worth a read for a collector interested in the Vth century athenian coinage.
