Chris,
There are very few of them around. We've handled about 10 and still have 4. It's very hard to price something so rare and 'market value' is questionable. Put it this way, wouldn't part with any of mine cheap.
Barry Szamboti has told me before that he thought Libras were some of the finest cues ever made. To me, that's a pretty powerful statement.
It's a real shame that the information I compiled and sent in twice for this Blue Book 3rd edition didn't make its way to print. Not to mention the example cues that were photographed in Chicago. Bummer.
