Yes, it is well worth the $30. Even if the average price for one individuale coin is only $5, you got your monies worth. I see a couple in the group that should clean up well and be worth the $30 alone. Good luck. Keep us informed once you receive them.
This lot has two values. The coins are, on average, worth the $2 each. The practice learning to ID them will be a lesson worth several times that. You have Greek, Roman and Byzantine. Some will be easy; some less so.
I really like buying lots like this - and yep, I'd say it is a good deal. With all due respect to Doug, I'd guess several of those I think would be worth more than two bucks - the Decanummium from Constantinople and the Philip II AE for instance. Two bucks average maybe, but I see a couple of gems. And is that a silphium plant I see on the reverse of one of 'em? Those types always go way outside my budget. I'd love to find one in a lot.
$30 divided by 16 coins is s tad under $2 so the answer to the question is they need to be worth an average of $2 to be a good deal. They are. I still believe the best thing is the experience of IDing them so we should not give answers until requested. I am not a botanist but I saw no Silphium. I might be wrong. Perhaps we have a specialist here than can ID that one. It would make a big difference if you are correct.
Actually, all 5 greek coins were identified by the seller, its supposed to be: Antioch ad Orontem, Syria, AE 3.72gr;16mm. Semi-autonomous, AD 68-69 (under Galba or Otho). Head of Apollo right / laurel branch.
