Why Sardina doesn't have sardines, I'll never know...

The value of the land depends on the value of the goods, which is as follows:
dyes 50, gems 50, spices 50

furs 40, glassware 40, honey 40, ivory 40, silk 40, sugar 40, wine 40

cotton 30, grain 30, hides 30, linen 30, olive oil 30, pottery 30, wool 30,

butter 20, fish 20, salt 20,wax 20, wood 20


I think it'd be interesting to invent your own goods. For instance: Rome, Malta, and Ile de France (Notre Dame) could all have Crosses or Religious Paraphernalia as a tradable good, or some of the Novgard lands could have Brides to trade. Just a thought.
