Sorry, I don’t know much about Byzantines or Arab-Byzantines. But your first coin resembles this “Arab-Byzantine, Pre-Reform. c. AD 650. AE-Fals. Emesa (Homs) Mint.” https://www.vcoins.com/en/stores/an...aefals_emesa_homs_mint_vf/564158/Default.aspx There’s a thread about these types here: https://www.cointalk.com/threads/islamic-series-dawn-of-islam.269408/page-2
