yep, lots of things comparable Mike.
When I was a kid (60s/70s) you could collect cigarette cards, coins sold by the likes of Shell and Esso, football figures, and robertsons jam golliwogs (not exactly pc now, which makes them all the more valuable !)
All of them were to get the parents to buy more of whatever the product was to keep the kids happy

Between myself and my sister I think we collected most things going
None of them have ever made that sort of money though to my knowledge.
