 When the first new hundred-dollar bills are issued to the public on Oct. 8, the new “100” in the lower right-hand corners will shine in iridescent gold—a flashy touch to foil counterfeiters and lend the new notes some style. Currency collectors pay handsomely for what they call “fancy” serial numbers—digits that they perceive as unusual or special. The simplest fancy numbers are the early ones: The redesigned $100 note with serial number 00000001 is likely to fetch $10,000 to $15,000, according to Dustin Johnston, director of currency for Heritage Auctions in Dallas. One collector, a Nashville songwriter named Dave Undis, has cataloged fancy notes and presented a taxonomy on a website, coolserialnumbers.com.

 9-digit 100000000 note - any size/type/denomination 
 
 ...and we're always looking for other cool stuff. “The number 4 sounds like ‘death,’” Johnston says, “but I can’t think of anyone giving solid 4’s to an enemy.” Americans like 77777777’s, and a solid-7 $20 sold in 2009 for $528. A certain kind of numerically obsessive patriot has collected a 07041776 bill, to honor the signing of the Declaration of Independence. Dates can also be collectible, such as 07041776 and 09112001, owned by one collector, the Globe notes. Nonhistoric dates could also be valuable, like 04171982 – if you can find someone with that birthday or anniversary. “If you look at a dollar bill, the number can just jump out at you,” Undis says. For them, money can buy happiness—as long as they don’t spend it.
– We are a couple of weeks away from getting our newly designed $100 bills, and when they arrive on October 8, some will actually be worth $1,000 ... or more. No, the government isn't slipping in an extra zero. But it is including, as always, an eight-digit serial number. And as the Boston Globe explains, currency collectors will pay big if the numbers are "fancy." That's the collectors' term, not the Globe's, for serial numbers that fall in a number of categories: there are "low" (00000001 through 00000100), "ladders" (43210987), "radar' (43788734), "solids" (33333333), and "repeaters" (82118211). Then there are random ones: 31415927 (pi) or 07041776 (read that as 07/04/1776). The low number ones are among the most valuable, with new $100 bills with 00000001 expected to sell for as much as $15,000. (Before the serial number you'll see one or two letters; these indicate which Federal Reserve bank issued it. As such, there can be more than one bill in any denomination with the same serial number in a given year.) So how do you get your hands on one? It helps if you have friends in high and very secure places. Bank employees, especially vault workers, are typically able to swap out a normal bill for a fancy one, says the director of currency of a Dallas auction house, and since bricks of money are marked with the serial number range, they can spot the bills fairly easily. But no one is going to become an instant millionaire: Bills in the 00000001 to 00000100 range are specifically split up. Still, feel free to pull out your wallet and take a look: Philly.com notes that CoolSerialNumbers is looking to buy these bills. (Click for another wild money story.)
