That *could* be it; I'd heard a few different versions of the story that 
some copiers would not do currency, and naturally the banks themselves are 
going to be less than forthcoming about their techniques (just like in the 
crypto world).

Personally, I was baffled about copiers refusing to print greenbacks; 
aren't they all the same colour anyway?  I can just imagine the algorithm:

    if hue_is_greenback
	select from (refuse, greyscale, invert)
	    with optional call_SS()

against which the obvious attack is of course:


Sorry for my horrible pseudo-code...
