Ah, yes. (That would mess up a \XeTeXglyph-based definition too, btw.)

Try
	\renewcommand{\textdollar}{\char"0024\relax}
That should ensure that as TeX is reading the number, it stops where 
you want and doesn't continue reading if the macro happens to be 
followed by digits.

Or you could use
	\renewcommand{\textdollar}{^^^^0024}
as the ^^^^ notation reads exactly 4 hex digits, if I remember right.

(147712 is the decimal equivalent of hex 0024100, in case you wondered 
where that came from.)
