I was given a stash of bowling balls and askedto determine their value .some was prety basic (original black Angle) but the others might be attractive. They include:

 - gold rhino pro
 - critical mass
 - purple rhino pro
 - messenger ti

they are clean, rh original drill, 15 lb. Most are basic stack drill of the era witha small weight hile. Any thoughts on value would be appreciated!!!

On Ebay you will get much more than the what was posted above.

That Gold Rhino Pro might get you close to $100.   I have on a few occasions sold them for $60 to $100 depending on condition.

The Purple Rhino Pro might get you $30 to $50

Critical Mass $30 to $50

Ti Messenger probably will not get you anything.  You might clear $15 to $20 after shipping.  Still worth a list on Ebay.

The Gold Rhino depending on the alignment of the planets will get you $40 to maybe $100. The others likely far less. Probably $40 shipped on the purple rhino and the CM with $0-30 shipped on the messenger.

It all depends who sees them and wants them. If you happen to post it and a couple people want them on Ebay they could get into a bidding war. Just never know.
