Black Powder Bill Cody Replicas Price value?

Hello, was wondering if anyone would be able to help me out on the price of a box set , Comemorative black powder Buffalo Bill Cody 44. cal black powder pistols? They are #1 of 5000 in series and say made in Italy on the barrels. They are chrome with pearl handles in a wood display box. Also is a picture of Buffalo Bill , and on the box his name and birth and death dates. Also included is the replica holsters and stock but to make the pistols into a rifle. They were never fired and are in pretty good shape. If anyone knows what this set would be worth would be a big help. I can pick up the complete set up for $450.00 , too much? Please let me know what you think, thanks Que-quage.
