In The Last Jedi, we see Luke take the gold dice from the cockpit of the Millennium Falcon before reminiscing with Artoo. Later, he seems to give them to Leia on Crait, but it's eventually revealed that those are a Force projection.
Is there any evidence of what happened to the actual set of dice? Did Luke replace them in the cockpit before Rey and Chewbacca went back to the Resistance, or are they still on Ahch-To?
The dice were removed from the cockpit long before The Last Jedi. Their last chronological appearance in the original trilogy was in the "Star Wars Holiday Special," which reused some footage of Han and Chewie in the Millennium Falcon that was shot for the first movie. You can see from this wide shot of the ship's cockpit from The Empire Strikes Back that they are not present.
Nor are they there when Lando is flying the ship in Return of the Jedi.
In The Last Jedi, the dice were imaginary all along. Luke was just thinking back to the ship as it was at the time of his first adventure.
