Whatever someone is willing to pay for it. That will depend on condition and exact configuration. Value range from a few hundred to multiple thousands of USD.
This is probably a "Risley" Colt 45. What is the serial number on it. Probably something starting with a 2.
I could find only a Bradford Mint replica non-firing rifle which was selling on EBay for $100. From what I could gather a non-firing, strictly decorative Colt 45, depending on the condition, can be around that price. The real firing gun copied exactly from Wayne's own Colt 45* can be upwards of $1000 or more if you can find one and it's in good condition. *The Colt Company made the Colt 45 replica just for Wayne which was exactly like a the late 1800's or early 1900's Colt selling at that time. The only difference was the firing pin (I think). I know little about collectable guns but I know Wayne did, the photo of his Colt was a beauty.
