Honest question. Who doesn't know what their guns are worth?
I know what mine are woth (To Me) and what I paid for them. Therein lies part of the problem. Some of the prices are sentimental and the owner sometimes feels like, "if you want my **** you are going to PAY for it" mentality and add personal values to real values.
My take on this so far, is go with your gut? basically any weapon is worth what someone will pay for it. I completey understand that.
So, I have a pistol I paid $312.00 for back in 1982, it stayed in my safe for 30+ years and only fired 20 or so rounds through it. Does that justify an $900.00 price tag? Just an example. I really do have one but, it's not for sale.
