Magnum, P.I., Season 7

Magnum:
[narrating] My grandfather was one of the world's great collectors. He collected souvenirs, stamps, and friends, but his prized collection was a stack of uncirculated currency: all silver certificates, all two-dollar bills. On my 13th birthday, he gave me one of them and told me to read the serial number. It was my birth date, and in time it became my "Lucky Two". I'd carried it with me ever since… until last night.
