Low serial number bills, typically those with five or more leading zeros (e.g., 00000001–00000999), are highly collectible and often worth 

 to over 

 depending on condition, rarity, and number of zeros. Uncirculated notes with 4–7 leading zeros command the highest premiums, with "00000001" often valued at over 

$1000 to over $15,000.  Here is a great opportunity to own one on the lower end with equity in your purchase.  I have two listed, so buy one or both.
