I recently purchased a hero fx bladed Daisy Ridley and Mark Hamill screen used lightsaber from The Last Jedi. I am slightly concerned that just a COA from heritage auctions is not enough provenance for this screen used prop? Am I making a mountain out of a mole hill or should I be 100% comfortable with completing the purchase? Link to the auction/lightsaber below. Thank you in advance for your help/suggestions.
