Oh boy, now you're in for it. Welcome to the T206 of the PCL. I've been following the cards since the 1980s. There are so many ways to collect Zeenuts, you're gonna have so much fun. You might want to search online for checklists. In 1929-30, the keys are HOFers Gomez, Lombardi, Nevers (football HOF), and popular guys and PCL legends like Buzz Arlett, Ox Eckhardt, Prince Henry Oana, Jimmy Reese, and many, many MLB players like Frank Crosetti, Bob Johnson, etc. As someone else noted, the coupon cards are highly prized; probably 99% of the cards do not have the coupons. if you see a famous last name on a Zeenut, odds are it is one, or his brother, cousin, son, uncle, etc.
And a card
