The value of a 1993 US 1 dollar bill is still 1 dollar. However, its rarity can influence its numismatic value. Uncirculated 1993 $1 bills in excellent condition can be worth more than their face value to collectors. For example, according to USA Coin Book, a 1993 $1 bill in uncirculated condition can be worth around $1.50 to $2, while a star note (a bill with a star symbol after its serial number) could be worth up to $5. It's important to note that the actual value of a 1993 $1 bill may vary depending on its condition and the buyer's interest.
