Blank flan for an AE4 of Zeno or Leo. Blank/Blank. Very unusual and rarely found. 7mm, 0.42 grams.This particular piece comes from a hoard of very late AE4's (mostly of Zeno and Leo). A number of pieces in the hoard seem to be completely unstruck. It is not possible to know if these are official pieces, unstruck by mistake, some sort of an emergency issue or ancient counterfeits. Since they were found alongside the properly struck coins, these blank flans were probably accepted as normal coins.
