It depends on a lot of factors.
The first is the condition of the ring. If it is bright and shiny with no scratches, chips, breaks or losses, it will be worth more than a ring that has any such defects.
The second factor is authenticity. Many times in the last century and a half, jewelry makers created fake coin jewelry by making molds from real coins and then recasting the coins using lead and then plated or painted them gold or silver. If you have one of these rings, it's only costume jewelry.
Finally, if it is legitimately 9 carat gold, it may still not be worth that much. 9 carat items can't even be sold as gold in the US, although they can in the UK, because they have very little real gold in them. 9 carat gold is only 37.5% gold and the rest is copper or nickel, two metals without great value.
So, 9 carat gold is worth 37.5% of solid gold at best, and even at today's prices, most scrap gold buyers would not want to bother melting down and refining the tiny amount of gold in a ring because it would cost more than they would be able to sell the gold for.
