Useless items found while moving, so far:

1) Bus transfer from 1994, before the Metrocard era.
2) $4 Canadian; smaller amounts, NIS, sure to come.
3) My high school ID card.
4) Countless receipts for sub-$5 (American) items. Muffins and coffees.
5) Flared jeans. (Useless, of course, because it's 2007).
