this reminds me a bit of the Better Call Saul episode where Jimmy learns finds out that the Bavarian Boy Hummel figurine on display where he used to work is worth a fortune.

He then stole it and swapped it for a fake and sold the real one for a ton lol

still, it's hard to predict but one thing we have now is parents are passing down the nostalgia and keeping it alive and a lot of the legacy brands are staying with the times doing movie tie-ins and stuff
