If it's expired for less than one year, you can transfer the balance using a Metrocard machine or by asking any station agent. If it's less than two years expired, you can ask a station agent for an envelope so you don't pay anything and they'll mail you a new card with the balance. Have done this a few times with old cards– they'll even combine the balances onto one if you ask.
