A lot depends if they are in 100% condition and if they have the original boxes and papers. IF they have all of the original boxes and papers, then they will be worth about $550 each, if you can get it. No boxes/damaged boxes/no papers/damaged papers subtract from that, considerably, maybe even $100 each.
The consecutive serial numbers may add saleability, but apparently do not add value.
The presentations box adds value, but only really if it is genuine Colt; the same goes for the accoutrements, except that the missing powder flask will deduct 20% from their cumulative value. Otherwise, I was unable to find a value for this.
