I draw a somewhat different conclusion.
I think the evidence of the bird stamps shows that the cedi sign has
a significant typographical history in Ghana, showing similar
variation to the storied history of the dollar sign. It is also clear
that the cent sign and just a capital 'C' are common fallbacks
for it, even in official documents. But that would make sense, because
the cent sign and capital 'C' are easily available, both in fonts
and in character sets.
The evidence presented in the stamps is at least as good as the
evidence we used to encode the guarani sign and the austral sign,
and I don't see a good case here for unification with U+20A1 COLON SIGN.
The cedi sign is the kind of decorated Latin letter symbol that we
fairly regularly assent to for encoding as a currency sign, and
it makes sense to me to go ahead with encoding it, if somebody
feels strongly enough about it to put the relevant proposal
together. Documentation for it should indicate the relevant information
about the range of glyphic variation, as shown in the bird stamps.
Something that people have not mentioned so far is that one of
the reasons that currency signs are separately encoded as
symbols is that they have a distinct property: gc=Sc. Graphic
constructions involving ordinary letters with combining overlays
might appear acceptable, but would end up with the wrong properties.
The potential drawback, as already pointed out, for encoding
a cedi sign is that the already established fallback practice
of simply using a cent sign (or a 'C') for the cedi will have
a lot of inertia. Adding a cedi sign now, which might be
available in earliest implementation a couple years from now,
and then take a considerable amount of time before such
implementations could be widely available in Ghana, would mean
a very long period of transition where both the fallbacks and
the new cedi sign would be in use. This might *cause* more
problems than it would resolve.
