I have 3 coins and am unsure if they are Alexander or Lysimachus. Would also appreciate if anyone could recognize the mints. Thank you!
First two are not Alexander the Great, but are posthumous. The first looks like Price 433, so Amphipolis under Antipater, Polyperchon, or Kassander. The second looks like Price 1836. Kolophon under Lysimachos. The third is Lysimachos. You can look up whether it's lifetime or not, but it does look suspicious to me.
