Well, in plain TeX \$ is simply defined as \char"24, so it should print 
a dollar sign in any normal font. But LaTeX may do something different 
with it.

It's not quite the same issue as the accent commands; at least the 
legacy TeX fonts support the standard character code for dollar, so a 
definition such as \char"24 (or changing the \catcode so that $ simply 
prints as itself) should access the right glyph in anything except 
special legacy symbol fonts. The trouble with the accent commands is 
that the CM fonts have accents at non-standard code positions and so 
the macro definitions are inherently font-specific.
