It was the # symbol that was replaced by £ in the GB version of ISO-646,
and on British keyboards.  The $ sign remained.  (Also ~ was replaced by
an overbar ‾, but I've no idea why.)

The $ symbol was kept in most, but not all, ISO-646 character sets.  It
was more common to replace characters like # { } [ ] | and ~ , all of
which are still there in C (but have trigraphs).

On a related topic, what is the rationale behind the choice of
characters allowed in universal character identifiers?  There seems to
be a vague attempt to allow "letters" but not "symbols".  Surely
allowing symbols like ¤ £ and § would be ideal for the kind of thing Alf
has in his library - characters that would not conflict with anything
else, stand out clearly, and can by typed easily on many keyboard
layouts (even with Windows).

Perhaps € would be a good choice - it is in the list of allowed Unicode
identifier characters.
