XRF analyses of electrum coins of 7th — 4th cc. BCE: coin hoard (hoards?) or several groups of coins

The subject of the publication is a group of electrum coins of Mysia — Kyzikus, Ionia — Lesbos, Mytilene, Phokaia, and Erythrae. The coins are 83 in number and were found together in a shipment of smuggled traffic. The numismatic term coin hoard, in this case, is not preferable by the authors and the group of coins is called coin pile. Given the need to prepare expertise for authenticity, some of the coins were analyzed for their metal composition. Detailed information is represented on the identification of coins and X-ray fluorescence analysis. In a catalog, the coins are arranged for convenience following thematic and chronological order.
