Hey Joe. Going rate is about $100 per ball for ivory carom balls 2.25" or better in good condition without the original wooden box. If I were buying 6 at a time, I would be asking for a quantity discount. eBay doesn't allow ivory sales, so the ability to sell is tougher too. If it were me, I would have paid $90 tops for the example that you posted. That's just me. Use your negociating skills to get yourself a good price, then enjoy. Mr H
