A $20 US bill known as the “Del Monte” note coveted by currency collectors is up for auction — and is expected to fetch tens of thousands of dollars. The 1996 banknote features a Del Monte fruit sticker with the produce code #4011, for bananas. The sticker somehow ended up on the bill in the middle of the printing process, and as a result, a portion of the treasury seal and a serial number is printed over it. "Whenever we see something applied to a bank note, it's almost always applied afterwards. Kids put stickers on their banknotes," said Dustin Johnston. "What's unique about [this] is that we know that it was applied during the printing process." The Del Monte note will be auctioned off Jan. 22, and the auction will be streamed on Heritage Auctions' website. The current bid for the note stands at fifty seven thousand and five hundred US dollars (or seventy three thousand three hundred Cdn). Once a buyer's premium is applied the total cost comes to $69,000 USD ($88,000 Cdn).
