I got them when we were in Zimbabwe years ago. I think I paid $5 each for them. Funny thing is they are going for substantially more on Ebay now. Inflation, I guess.
I still have 1 trillion Zimbawean dollars. I keep them as one day they will be at a 1:1 rate with the USD. And then I will be a billionaire when I sell them. I learned that from the crypto traders. As I still keep these Zimbawean dollars I still made no loss till today.So the $10K that I paid for them earlier are still safe.
