A similar problem came up for me some years ago. As the others proposed, 
I convert these strings into integers, using cent values only. You could 
even use tenth of cents to meet commercial standards.

You can write yourself some handy functions that do the conversion into 
integer and from cents back to currency strings the way you need it for 
your locale. Another way might be Format - but I never needed to dive 
into that one, so I know little about it.
