method $tag overrides nothing ??

Make sure you clean your build.

What version of scala are you using?

I'm getting the compilation error "method $tag overrides nothing" at lines 2
and 3 for the case objects with the following:

   abstract class Currency(val name: String)
   case object USCurrency extends Currency("US")
   case object CanadianCurrency extends Currency("Canadian")

If I make the class Currency a case class, then I get the error only on line
1 for the class.

What does this message mean? If I recall, $tag, defined on ScalaObject, is
there to help with pattern matching.

I do not think you are -- it is likely you are somehow using a mix of
2.7.3 and something more recent. The code you supplied works fine on
either 2.7.3 or trunk individually, but since $tag was ditched a few
weeks ago, a mix will cause you problems. (A mix will almost always
cause you problems, but this would be one of the most visible.)
