Between stealing the gold coins from that travel agency and snatching the 13th chapter of the Mosconi Codex, Neal Caffrey (Matt Bomer) has been a very naughty boy this season on White Collar. And unfortunately his crimes may be catching up with him.

In this exclusive sneak peek from Thursday's episode (9/8c, USA), Peter (Tim DeKay) reveals that he's found one of the gold coins Hagen (Mark Sheppard) forced Neal to steal for him in the season premiere. Even worse, Peter reveals to Neal that he's so determined to solve the crime that he put those coins on an FBI watch list.
