Best way to sell lots of late 90s inserts

[Old Chesapeake]

I'm organizing my basketball card collection to sell. Around 2500 late 90s insert cards. 2000 low value - $20 or less (of these around 150 are kobe or MJ), and about 400-500 worth $20 up to $12K (Of these, around 100 are MJ or Kobe).

So my question is, what's the best way to sell this? I was planning to sell all the low value cards as one large collection, then the low value MJs and Kobes as separate lots, then $20-$50 as a smaller collection, then the rest will probably go to consignment as singles.
