What is a misprinted bank of England 20 note with queens head on both sides?

A misprinted Bank of England 20 note with the Queen's head on both sides is a rare and valuable error note. The Queen's head should only appear on the front of the note, with the reverse featuring an image of the Bank of England. Misprinted notes like these can occur during the printing process, and they are highly sought after by collectors and banknote enthusiasts.

The value of a misprinted banknote can vary depending on the specific error, its rarity, and its condition. In the case of a 20 note with the Queen's head on both sides, the value could potentially be significantly higher than the face value of the note. It's important to note, however, that the collectability and value of misprinted banknotes are subjective and can fluctuate over time.

If you come across a misprinted banknote, it's advisable to consult with an expert or a reliable banknote dealer to assess its authenticity and determine its value. Misprinted banknotes can be a fascinating and valuable part of numismatic collections, but it's important to handle and authenticate them with care.
