What $2 bill is worth $20,000?

Excuse me, but I couldn't help but notice the intriguing statement that a $2 bill is somehow worth $20,000. Could you please elaborate on this? Is this a reference to a particular $2 bill that has gained exceptional value due to its rarity, historical significance, or some other unique factor? Alternatively, is this a hypothetical scenario or a reference to a cryptocurrency or digital asset that's being compared to the face value of a traditional $2 bill? I'm quite curious to understand the context and reasoning behind this claim.
