Factual error: As the boy dies, his hand opens and coins roll out. Included are Washington Quarters (first made 1932), Jefferson Nickels (1938), and Roosevelt Dimes (1946). (00:15:45)
Other mistake: Several people, believing a treasure is hidden inside the Trails End saloon, are tearing the wooden building apart. To stop them, Joe pulls out his gun and fires a shot into the ceiling. Even though he held the gun at a 75-degree angle in front of him, the falling dust and plaster land directly on top of his head.
Other mistake: The episode opens with Ben Cartwright ascending an outdoor staircase to a land office. The sound of a howling wind can be heard but no dust or leaves are blowing and all the surrounding bushes and trees are motionless.
Blind Hunch - S13-E9
Continuity mistake: Jamie and a blind man are riding side by side on horseback along a trail. Upon hearing the sound of a bird, the blind man identifies it as a black-tailed magpie. Jamie looks up to see the bird. The next shot, obviously from stock footage, shows a bird sitting on a branch of a tree with no leaves. In the scenes with Jamie and the blind man, every tree is fully grown with leaves and there are no bare branches.
