The newly designed $100 bills will be released on October 8th, and some of these bills will be worth upwards of more than $1,000! The serial numbers printed on some of these bills will be very valuable to collectors, and therefore will be worth a lot of money. Some bills will even be worth up to $15,000! The International Business Times lists the serial numbers that will have value: "The following are some of the subcategories: solid, which means the numbers are the same, like 11111111; radar, which is the same number backward or forward, like 13466431; repeater, which means both halves are the same, like 12791279; super repeater, which is a pair of numbers that repeats four times like 55553333, a ladder, like 12345678; low, 00000100 or lower; high, 99999900 or higher" (IB Times). When the new bills are released, it might be worth your time to check out the serial numbers to see if you have received one of these rare bills.
