Why is retro so expensive?

I'm curious, could you elaborate on why retro items, particularly in the realm of cryptocurrency and finance, tend to command such high prices? Is it due to scarcity, sentimental value, or perhaps a unique combination of factors that drives up their desirability and market value? Additionally, how does this phenomenon compare to other collectibles and investments within the broader financial landscape? I'd love to gain a deeper understanding of the intricacies behind the elevated pricing of retro assets in our current economic climate.
