I think the +1 for each resource somewhere is fine, but I also think that it's very important for quarry/pasture/plantation/camp to get the same bonuses from techs that farms and mines do, including the freshwater/no freshwater split. But I hope we don't increase beyond that. I think +2 faith for resources on the temple is a mistake, it shifts too much of the value of the temple onto resources rather than the building itself. The mint is the weirdest of all the buildings, because it is something where the original design was purely to boost resources; the building literally did nothing else. It doesn't really fit any clear gameplay need, it's basically the same as the market but tailored to particular resources. Why do there need to be 2 gold boost techs there? Another thought would be to merge the bonus into the caravanserai. I think this makes sense. The other question I would ask is: are there cases where you would want to build them in different types of cities? And the answer is really no, they are both for unit production cities.
