Continuity mistake: During the show's opening credits for the entire run of the series, when Tony drives up to the NJ Turnpike toll gate, the lane 7 machine spits out a toll ticket, and Tony reaches for it. It then cuts to a close-up as Tony grabs hold of the toll ticket, but this ticket machine is now different; note all the stickers. The close-up was shot at another lane's ticket machine.
Continuity mistake: At dinner, when Meadow gets upset, she leaves the table and heads upstairs, so Carmela leaves the table and follows her daughter. Then, when Livia gets insulted, she tells Junior to take her home, and she too leaves the table. The problem occurs when Tony tells Junior, "You mangia, Uncle Jun', she'll come back," and in the next shot facing Junior, the reflection on the door shows Carmela and Livia are still seated at the table.
Visible crew/equipment: After Tony gets written up for speeding, it then cuts to Bryan Spatafore parking his pickup at the curb, and just as the pickup's door opens and closes, we can see the reflection of the boom mic on the vehicle's door and window.
Deliberate mistake: While Tony stands beside his car, the first assassin shoots at him, and when Tony dives into the front seat we see the car's dashboard. After struggling with the second assassin, when Tony crashes into the parked car, in the shot from inside the car, there are two issues: the car has a different style dashboard with no air vents, and the rearview mirror is missing; then it reappears.
Visible crew/equipment: During the dinner scene, in some of the shots facing Junior, the reflection of the boom operator (wearing a watch) holding up the boom pole/mic is visible on the glass, toward the top left side of the screen. Additionally, in two shots facing Junior (POV beside Carmela's right shoulder), we can see part of a black reflector screen (collapsible type) between Junior and Carmela.
Continuity mistake: When Janice goes to Livia's mailbox and retrieves the envelope with her disability check, the words "TOTAL DISABILITY" only appear on the check in the close-up, but not in the previous shot. Additionally, the silver screen door is gone between the first wide shot when Janice pulls the mail out of the mailbox, and the next close-up as Janice looks through the mail in her hands (she did not open the screen door between shots).

Visible crew/equipment: While Sal and AJ are at the batting cage, Matt starts telling AJ about the German philosopher Nietzsche. As the camera moves backwards in this dolly shot, we can see two metal T-marks on the ground, as well as the dolly track at the left side of the screen.
Moe n' Joe - S6-E10

Revealing mistake: After Tony's unsuccessful meeting with Johnny due to Christopher's inability to keep his mouth shut, while Tony and Chris are driving past stores, we can see the reflections of the filming equipment attached to the roof of their vehicle.
Visible crew/equipment: Paulie and Christopher convince Tony to head out and try to locate them, and to bring them food as well as shoes for Paulie. In the wide shot, just as Tony puts on his shoes and tells Gloria, "I gotta go," there's a red T-mark on the wood floor at the lower left side of the screen.

Continuity mistake: When Tony shows up at Livia's house with a bouquet of flowers, in the exterior shot note the transparency of the screen door's glass, the front door silver-color knob with its back plate, as well as the deadbolt cylinder. As Tony enters the doorway in the next interior shot, we cannot see out through the screen door's glass, the door knob is gold-color, and both the knob's back plate and the deadbolt cylinder have vanished.
Answer: That's not Jimmy, just a look-a-like. Jimmy's short and stout, the guy in "Christopher" episode is tall and medium built. The hair is also different.
