#USStablecoinBill * While challenge coins are valuable to those who receive them, they are not currency and are not typically associated with being placed on tables in a formal sense, except perhaps during a "coin check" where members present their coins.

In summary, while there's a rich history of coins being associated with US Navy ships, particularly the tradition of placing them under masts for luck or as a symbolic gesture, the concept of a formal "USS table coin Bill" is not supported by available information. It's more likely related to one of the informal traditions, commemorative items, or perhaps a misunderstanding of naval customs.
