Condition is everything. This sounds like it could be a 1911 Colt government model but serial number don't tell you everything. If it is a 1911 Colt GI pistol (that could have been made in 1917) it could be worth as much as $2000 in excellent condition to as little as $300 in poor condition. Take it to a reputable gunshop, pawn dealer or gunsmith and have them give you a better idea as to worth.
