Look for gun value website
 

Is there anything on-line like the Blue Book of Gun values? Googled it and came up with nothing.
thanks

Skinny, the auction sites will give you a good idea of what people really pay for guns- not what the book decides it's worth.
The ones I know of are Auction Arms and GunsAmerica.
I believe Auction Arms will let you review the past 6 months of sales. You should be able to get some reality based ideas from that.
