6% of a 1979-80 O-Pee-Chee Set

Last month I purchased 25 cards–roughly 6%–from the 1979-80 O-Pee-Chee Hockey set. This brings me up to 177 out of 396 cards.

Of course, when you still require the Wayne Gretzky rookie card for your set, you can have 395 cards and still feel like you are about a thousand cards short.

Nonetheless, I now have the second and third-best cards in this set:
 

#175 – Gordie Howe

#185 – Bobby Hull

I got a few other key cards, including…

#161 – Mike Bossy (Record Breakers)

#100 – Bryan Trottier

#215 – Bernie Federko

#145 – John Tonelli (RC)

#164 – Brad Park (Record Breakers)

#225 – Jean Ratelle

#1 – Goal Leaders (Bossy/Dionne/Lafleur)

Another 218 cards–plus a Gretzky RC–to complete this landmark set. In the meantime, I’ll continue to chip away at it, a few cards here and there.

QUESTION: At what point do you “page” your sets? That is, when do you put a near-complete set into pages? Do you get a certain percentage, like at least half? Or do you wait until you have every single card? Or, do you not use pages at all…?
