I think pretty much everyone here who owns toys that are older than 6 years old are worth double what they paid for. Toys can go up in price pretty fast if they were popular enough.

I have a couple of Epoch Zelda figures that are like 10x what i paid for. Same with various Mega Bloks stuff, where just the minifigures can net you like 2x what you originally paid for the entire set

I also have some McFarlane Five Nights at Freddys sets i bought for my nephews that jumped in price 5x. Never gave all of them out, because i found out how cool McFarlanes building sets are.

This particular set goes for $50. Opened.
