FAQ
Reader questions
How can I quickly tell a 100 $1 bill from a fake in everyday use?
Check the color-shifting numeral 100 on the lower right, verify the embedded security thread with “USA 100” when held to light, and feel the crisp texture of Franklin’s portrait; these steps catch most counterfeits during routine transactions.
Does the series year on the bill change its everyday usability or only its collectible value?
Series years do not affect everyday usability; any genuine U.S. bill remains legal tender regardless of date. Collectible value may rise for certain series with low mintage, appealing notes, or notable errors.
Are older 100 $1 bills still accepted, and what should I do if one feels very worn?
Older series remain valid at face value if major damage does not obscure security features or the serial portions. Heavily worn notes can be exchanged at a bank to avoid handling issues, and especially tattered historic pieces may merit evaluation by a currency specialist.
What should I look for in serial numbers if I am curious about rarity or value?
Low serial numbers, solid repeating digits, or fancy patterns like radar or repeater notes can be more desirable to collectors, while star notes replace misprinted bills and carry collector interest beyond standard series details.
