This is going to be interesting, maybe. "In God We Trust" has been present on US paper currency since 1957 and is also the US National Motto since 1956.
Nonbelievers seek to take God off currency - Freedom From Religion FoundationThe Freedom From Religion Foundation, along with 19 other plaintiffs, is suing the U.S. Treasury for stamping "In God We Trust" on currency. Honorary FFRF board member Mike Newdow is acting as legal counsel in the suit, which was filed in the U.S. District Court for the Southern District of New York on Feb. 1.
The complaint alleges that the religious verbiage is proselytizing, discriminatory and a per se establishment of monotheism in violation of the Establishment Clause.
The complaint document itself, while I've only spent 10 minutes scanning it, looks like a very well researched submission with plenty of solid argument by the plaintiffs.
The complaint is summarised on page 78 of the document: That the declaration of "In God we trust" on the currency violates the Establishment Clause, the Free Exercise Clause and the Religious Freedom Act. They are seeking to permanently enjoin the defendants from minting/printing currency carrying this motto.
Incidentally, this is not the first time that the FFRF have taken issue with the motto.

I wish them well. Perhaps this will encourage us to fix the preamble in our own constitution.
