Welcome to CoinTalk, Jason! It appears to be a replica of an ancient Greek coin, specifically a tetradrachm (or other denomination, depending on the size of your item) of the Chalkidian League. Here are your images cropped, joined, and displayed in full for ease of examination: Here's an authentic example from CNG's archives. MACEDON, Chalkidian League. Circa 383/2 BC. AR Tetradrachm (21.5mm, 14.56 g, 6h). Olynthos mint. Head of Apollo left, wearing laurel wreath / Kithara; X-A-Λ-KIΔ-EΩN around; all within incuse square. Robinson & Clement Group H, 22 (A18/P19); SNG ANS –; BMC 3 = GPCG pl. 21, 10 (same dies); Hermitage Sale II 587 (same dies). Near EF, toned. Well centered and excellent metal.
