Vanguard Index 500 and Apple....I try to follow Buffets lead but with around 8 less 0's at the end of my investments...

Fossils, always liked em very valuable. Only have two. The wild boar mandible I found on the beach.

What do a ton of kids have an attachment to today?

iPads, iPhones. I think original copies in 30 years will be super hot. Will an operating system even be functional then? I don't know and that would be a huge factor but it's something different that I haven't heard discussed.

I collect Confederate Civil War artifacts. Rare, as the CSA produced fewer items than their northern counterparts, and much more of it was destroyed during/after the war. There is also a big market for GAR encampment ribbons and medals. Lately I’ve been adding signatures of Union generals which still sell surprisingly cheap (in part because the Union had many generals at various levels)

Buying Apple yesterday would have been a good thing....

But for collectibles, I am going with beanie babies!! Then I am onto pet rocks.
