I will ask again - can you show us the rest of the pool cue? Perhaps provide info on when and where you bought it? It will help point me in the right direction.
In 2011, there was a more intricate Vintage brand pool cue, brand new, for sale on AZB for $140. It was Vintage brand model VT95. The guy said they retailed for about $225. He couldn't sell his at $140, dropped the price to $100, and still didn't sell it. Here is the shitty picture:
Then, on eBay (2014) there was a Vintage brand pool cue, model 307, which sold for $51 USD. No pictures were available.
Used Pool Cue: Brand name Vintage Model 307. Measures 58 inches and weighs 19.3 oz.(according to my digital scale) Forearm runs-out 1/16 of a inch.(Last picture show the lift) Shaft rolls true and is straight.
Then more recently, this Vintage Brand Model IX pool cue sold for $70 in Farmington, NY.
I think this gives you an idea of how to value your pool cue.
