This could be something that you bought for a higher price than what most people would guess based on the item, or it could be something you bought for a normal price that has gained significant value as time has gone on.
What made me think of this question is a LEGO minifigure I got with my “The Hobbit: An Unexpected Journey” disc. It is Bilbo Baggins in a blue coat that was apparently only sold in that movie box only at Target stores. Even considering the exclusivity, I would have guessed maybe $10-20 for such a tiny piece of plastic, but there are sold listings on eBay from $80 to $225. I could possibly even get towards the higher end of that number since I still have everything in the original box in good condition. It’s not worth a ton compared to some other items people may own, but I think most people would not expect nearly that amount.
Not sure if these would be unexpectedly high values as most people know they fetch a little bit, but I have all my old N64 games still boxed with most of the original inserts too. The one I know most would be Conkers Bad Fur Day, that always seems to fetch a nice price.
A couple of my Funko Pop figures are possibly worth a few hundred but nothing more.
And I have the full set of Hobbit and Lord of the Rings Lego sets which I know go for a bit over the original price.
All cool collections! I have a few Funkos worth around $100 but probably wouldn’t sell them unless I needed to. Besides the LEGO Bilbo I mentioned in the description, I bought the Rivendell set towards the end of last year. I would like some of the old LotR or Hobbit sets, but they get pretty pricey.
N64 games are pricey enough, but with the cardboard? Might as well consider them an investment! Lol
