A Suitcase Full of Cash and a Yellow Clown Car - S5-E16
Factual error: In the closing shot of this episode, a pile of cash is down close up. The bills are current circa 2000s and the show is set in the late eighties. The bills didn't have the current security markings that we have now.

Other mistake: Georgie tells Mandy he'll soon be 18, in March. That same day, Sheldon says Isaac Asimov died - which happened on April 6, 1992.
White Trash, Holy Rollers and Punching People - S5-E21
Factual error: When Georgie goes to the doctors office with Mandy, when he walks in you can see a modern covid-19 safety poster behind his shoulder. (00:11:00)
Answer: It is shown numerous time in The Big Bang Theory and Young Sheldon that Georgir Jr is not the smartest kid going. They simply tell him Sheldon is getting a hair cut as it is believable. It's also shown that Sheldon has had the same style hair cut since he was 5. Since he is 9 in Young Sheldon, he's had the same style for over 4 years already. Easy to overlook that he hadn't actually had it cut after that long.
