This is a video of Youtuber openboosters finding a 1993 first print (Alpha) Magic: The Gathering Black Lotus while opening a vintage starter deck. There were only 1,100 Alpha Black Lotuses ever printed (with an additional 3,000 less vaulable Betas printed the following year), and can fetch up to $30,000. For reference, that's worth more than every car I've ever owned, combined, and I've owned over 40 cars.
Keep going for the video, but skip to 8:00 for the Black Lotus find. Also, the reason he flips the deck over at the beginning and the Black Lotus is the last card is because the rares were always placed on top of the deck when packaged.
Thanks to Prometheus and Hayate, who refused to help me counterfeit valuable Magic cards and now I'm afraid they know too much and will have to be silenced.
