I would map both numbers, and use different tags depending on the situation. When the old number is still visible (also when stroked through) you can use old_addr:housenumber
when the official number is not visible (or a different one is), you could use official_addr:housenumber. I agree with Alan that the number on the ground should go in addr:housenumber
