Yes, but the important difference is that on the whole, the stock market goes up. On the whole, the collectables market does not.
The collectable market keeps growing with new products and new prices everyday. Something historically valuable will generally keep that value and increase over time (like the original Apple computer).
This is absolutely not true. If we pick a random item from the 1980s that was valuable at the time, the chances are it's worthless now.
