Investing in collectibles?

Curious to see if anyone else here invests in alternative assets like art, trading cards, books, etc. I was super into that stuff when I was younger and the returns over the past few years have been absolutely stellar (e.g., if you invested in certain Pokémon boxes ~5 years ago they have increased 5x-10x).

I just dumped my last IB bonus into a few different assets that I think (from my research/experience) have the best chance of 10xing over the next few years. And the great thing is that they are almost 0% chance of losing value (i.e., worst case downside scenario is being able to sell them at original retail price). Obviously there’s a lot more work involved with actually selling the assets at the end (time, fees, etc.) and they’re relatively illiquid, but you can make some crazy returns. I wish I had a full year PE bonus to deploy because there are plenty of good investment opportunities right now.

Also, just to be clear, I max out my 401k and have a bunch of money in a Roth IRA/traditional savings account - I feel like I have more than enough exposure to S&P/Nasdaq.
