Huge amount of helpful friendly knowledge to be had here. Blue Book is a good starting point for prices. Also, look at gunbroker.com and enroll for free and look at the advanced area for actual sold-prices rather than the often unrealistic asking prices. If your screen name here is an indication that you're a female you have an additional challenge. Meeting guys in parking lots to exchange IDs and cash and guns is a bit frightening in the real world. I've done it and even as a male who was always accompanied by a buddy or son it can be unnerving to say the least. If you want to be highly efficient I'd suggest enlisting a knowledgeable friend or two and setting up at a gun show and ask moderate prices and don't be quick to make bargain deals. I've seen a couple of estates moved that way.
