Question: What is the selling value of a building cost city cash?

I know the selling value of a building cost your coins is 10% of the original price, so how about the one cost city cash?

thanks!!

All I know is a River costs 3 city cash to buy and it sells for 300 coins.

Whether or not that 1:100 ratio holds true for the rest, I don't know.
