this is because string.replaceAll() actually works with regular expression patterns. The source of your trouble is that "$" is a reserved character in regex, which matches at the beginning of a line. The "pattern" of "$" is matching the line's start position, but doesn't actually match any text. Consequently, replacing nothing with a blank string does nothing :)
What you'll have to do is escape the "$":
// in Java, of course...
string.replaceAll("\\$", "");
The double escape character is necessary for the backslash to wiggle its way into the regular expression, past Java's own character escaping backslash.
