Ms. Artusa, a baseball-card collector since the 1970s, found something unusual in while opening a pack of baseball cards with her husband recently.  The usual looking insert card contained scratch-off code that pointed her to a Web site. Upon entering the code, the site told her she had won a card that featured a strand of Abraham Lincoln's hair, as well as his autograph.

"Abraham Lincoln? We thought maybe it was a mistake," says the 57-year-old accountant.
