VACollector, If you enjoy the human interface of selling high quality firearms then selling directly to the market through internet could prove to be very rewarding. Also there are a few trustworthy, knowledgeable and likeable gents - some of which frequent this board - who would prove to be a real and significant asset to ascertaining value, marketing and negotiating excellent financial return through the sale of the guns some of them even have the time and perhaps the inclination to do so. Sounds like you have a most impressive collection if you have the time I suspect that you could almost select the market and appropriate opportunity to sell each gun to the right person.
All the Best, Slate
