For anyone who might still have a $2 bill in their possession, you might want to check the US currency price guide to see if your $2 note might actually be worth much more than its face value. Last July, somebody sold a $2 bill on Heritage Auctions for $2,400 which was later sold at $4,000. It's not uncommon for old, historical pieces such as these Jefferson notes to fetch for high prices because of their rarity. Despite being manufactured at the same cost as $1 notes, it just wasn't circulated as much and they supposedly became notorious for being used in betting and bribery in the mid-20th century.
Although $2 notes continue to be produced, there are some notes which become collector's items because of certain factors like unusual serial numbers or having stars designated on them, called replacement notes or star notes. Moreover, because $2 notes are rarely used, some have encountered problems regarding the authenticity of the notes. The most recent incident happened in 2016, when a 13-year-old girl in Texas used a $2 note to pay for her lunch at the cafeteria. She was later detained as it could not be ascertained whether the bill was genuine or not.
