The concensus I think is that if a road has had a "C" number added 
purely as a bookkeeping reference by the council, but doesn't appear on 
any signage, then a tag such as "official_ref" or "admin_ref" makes more 
sense.  See previous discussions here:

(and others linked from those threads).

suggests more traction for "official_ref" over "admin_ref".


However yours looks more interesting than the usual OSM "C" road:

It looks like it was previously a B road (OOC maps suggest the B1268) 
and kept its number when it was downgraded.  If it's a real ref on a 
real road sign I don't think that anyone would disagree with it being 
tagged with a C road ref.

I've seen at least one other signposted one in North Yorkshire (north of 
Castle Howard somewhere - I suspect there are more) so it's not unique.

Cheers,
