80's cards worth getting graded?

I recently bought the complete sets of topps from 81-86 and was wondering if anyone had any suggestions of cards that would be worth getting graded.

Iv only really been following NFL since around 2011 so I don't have a massive knowledge of older players that would be worth getting graded. So far the cards I am thinking of getting graded are

81 Joe Montana
84 Dan Marino
And the 86 Jerry Rice

Are there any others worth looking at getting graded?

There is a Steve Young Rookie card in the 86 set.

84 Elway
