The focus seems to be much more on the incantation bowls than on coins. Which makes perfect sense, since they're obviously far more important historically, and require far more scholarly analysis, than any coin that may have been found. I do like the fact that the language of these incantations parallels the language of divorce agreements.
For sure it's mostly about the incantation bowls. Very early ones are apparently known to be the earliest translations/uses of some Judaic text. Those who know nothing of these wonder their use. They were placed upside down to apparently entrap demons inside, where the Hebrew inscription is. Mostly they are Aramaic but quotations are in Hebrew, generally speaking. I spent a few minutes thinking about this but have come to the conclusion I do not understand. Hopefully I never need to.
