Note: What is the 'mystic staff' that the pig is standing on? Sear in "Greek Coins and their Values" calls it a bacchos, but does not clarify what he means by that. On some examples, like this one from Coin Archives, it look like a sheaf of corn bound together, perhaps around a central staff, and it seems likely that this depicts a long torch.

"Lloyd T" on the Forum Classical Numismatics Discussion Board wrote on 18 March 2009: "It appears that the current popular description of the Eleusis bronze reverse in terms of a pig standing on "mystic staff" is incorrect. The item on which the pig stands is a long torch, as identified in the preceding posts, and this was understood in the early-mid twentieth century. Its identity seems to have been lost in many recent numismatic catalogs that usually describe the problematic element of the reverse of this coin type as a "mystic staff". In the early twentieth century this long torch appears to have been considered to be most likely, though not certainly, to be a "bacchos" in ancient Greek. As a descriptor of the item on the reverse of the coinage of Eleusis, the term "bacchos" appears to generally have fallen out of use in the late twentieth century."
