How much is a 9 karat gold ring worth?

It only has 37.5% Gold in it as oppposed to 24k which is pure gold. So on this scale I would think the equivalent of what you might pay for a good SS ring. Since there are no other info to give a true basis I would not pay that much for it. It still depends on the gold content and weight etc. To me 9% is almost no gold content at all or maybe the same as a gold overlay.
