The blue seal on a 1934 US $5 bill does not affect its value. There are two types of seals found on US currency: gold seals and blue seals. Gold seals are found on Federal Reserve Notes, while blue seals are found on Silver Certificates. Both types of notes are considered to be legal tender and have the same value, regardless of the color of the seal. The value of a 1934 US $5 bill is primarily determined by its condition, rarity, and series. A 1934 $5 bill in average condition can be worth around $10 to $20. However, uncirculated or higher-grade notes can be worth significantly more, potentially reaching prices of several hundred or even thousands of dollars.
