It wouldn’t surprise me. The original bionicle figures have went up in value since they were discontinued.
I used to have a few figures back in the day, but I really only collected Lego Star Wars.
I have an unopened McDonald’s poly bag of a bionicle character which is probably worth something. I forget which character it was though.
The bag is a little crinkled, but it’s never been opened: I also found some Lego Galidor figures as well in the poly bag. Not sure if they are worth anything since they weren’t a popular theme, but still cool to have.
I had this guy too, but not on purpose, I got hand me downs from some older guy way back when I was 8, its head springs, right? I kind of lost and broke down the parts tho ):
