It currently contains:

CDIB card (proof that I'm partially of Native American decent or something)
AT&T prepaid phonecard with 120 minutes on it
Various Walmart reciepts
Social Security card

Black magnetic thing with phone numbers written in it
Two books of stamps
The key to this house

......

Yeah thats it.
