Continuity mistake: Near the start when Bond and Moneypenny are talking about gold, she throws his hat at the hatstand. The top of the hat is facing left as it flies offscreen, but when the shot cuts to it landing it's turned itself around so it can catch properly on the hook. Plus it lands on the hook furthest from the door, but when Bond leaves he picks it up from a closer hook.
Continuity mistake: In the first shots of the golf course, you see Goldfinger's Rolls parked to the far left of the main building, with Bond's car in the lot in the background. When the scene changes to the inside of the clubhouse store, the Rolls is now very close to the front of the store. At the end of the golf game the Rolls is back to the left of the main building and as the camera pans back you can see that the store is to the far right of the main building.
Continuity mistake: The T-Bird following Oddjob to the junkyard does not have fender skirts but does when they give up the chase and head back to the farm. (01:16:25 - 01:20:30)
Continuity mistake: When Bond is first put in the truck, it shows both of the larger trucks as 1964 Internationals, lead by a new Jeep CJ series with curved front fenders. In the next few shots, the Jeep becomes a 1950s version with flat front fenders, and the larger trucks are now darker green 1956 Fords. When they arrive at Fort Knox, the Jeep and trucks have changed back to the newer models.
Continuity mistake: The bomb is disarmed with 007 seconds left on the conveniently placed timer with big white numbers. Then, Bond says "Three more ticks and Mr. Goldfinger would've hit the jackpot." What? Well, originally, the timer would've stopped at 003, and the line would make sense, but later the powers that be decided to stop it at 007 instead for a good old Bond joke, and apparently never forgot to delete that line in editing. [The 3 clicks mistake is an interesting one as there are still in existence cuts of the film with the original 003 on the nuclear device timer. One contributor saw the 003 version in 1970 and was puzzled when the 007 version turned up on TV years later.] (01:40:40)
Continuity mistake: You can see when the black Lincoln that Oddjob drives to the junkyard is lifted to be crushed, it has no engine or transmission. (01:15:40)
Continuity mistake: After the game of golf between Goldfinger and Bond, Goldfinger gets Oddjob to show off his usually dangerous hat. He throws the hat at the statue and we see it fly off to the right of the screen, well away from the statue. Yet in the following shot, the decapitated head falls down next to the hat on the ground right by the statue.
Continuity mistake: Oddjob drives a '64 Lincoln into the junkyard. Then he walks away from a '63 Lincoln, which is the car that is crushed. (01:13:15 - 01:15:25)
Continuity mistake: The Aston has a dent in the side that comes and goes between scenes.
Continuity mistake: After Oddjob has knocked Bond out whilst he was looking for some cold champagne, Bond is seen lying in front of an open refrigerator door which has five small and one large bottle on the lower shelf. When Bond awakes there are now six small and one large bottles there. (00:15:35)
Continuity mistake: When Oddjob drives Mr. Solo to the airport, he drives him in a black car. After he shoots him and takes him to the scrap yard, then he has the car crushed in the compactor. When it comes out, it's the compacted remains of a car painted a lighter shade of blue.
