I am in the position where I need to sell my Colt Collection of 2nd Generation Blackpowder Revolvers. After speaking to auction houses I realize that between 30 - 40% will need to be reduced from the full potential value due to auction commissions and fees. I have sold through GB on my own with good success, but never a collection of 50 guns of the same theme. Do I lose any advantages not having the entire collection displayed at a big auction house? Any other comments are greatly appreciated.
