ARAB-BYZANTINE: AE follis (14.04g), NM, ND, A-3509G, countermarked tayyib on the reverse of a standard follis of Justin II (565-578), officina Δ, regnal year 10, VF on Fine host, RRR. The countermark is almost identical to the mark on standard Arab-Byzantine Scythopolis folles published by Amitai-Preiss, Berman & Qedar in INJ volume 13 (type A9a). This is first example we have seen with the tayyib countermark on a standard follis of Justin II, thus further evidence that the old folles of Justin II were still in use in the Baysan region nearly a century later.
