no idea on the total redeemed (or if they printed only enough to satisfy the redeemed quantity) , but based on my own experience , i'd dare say there are FAAAAAR fewer than there are for ANY other rookie in the set (i broke 4-5 hobby boxes and TONS of blasters ....i pulled 5 darko redemptions but a MINIMUM of a dozen and as many as 20 of EVERY other card including rookies)
I collect almost anyone else with ties to the state of South Carolina (especially ANY SC Gamec0cks) , + most parallels and rare 90's inserts
