I was given two two dollar bills for a tip tonight at work. The funny thing is that they are in numerical order and still attached or uncut one one end. Are these worth anything? Series 2003 A

The attached two dollar bills are worth more, but probably not too much if you only have two attached together.
You can read about the uncut sheets of bills on wiki. United States two-dollar bill - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/United_States_two-dollar_bill#Currency_tracking)

You could also check eBay and see if anyone is selling uncut sheets to determine if two attached bills are worth anything.
