I can't see a better way of selling than posting a big list with higher end comps (or even more expensive based on rarity) each card Individually. There's just no conceivable way I can see them doing better as a 520 card lot.

If a Cobb goes for $5000 that you have, selling it for $5000 is far better than selling the 520 card lot and the Cobb coming out to an estimated price of $4200. That's my mindset at least. And can be applied to them all imo. Eye appeal is also huge (obviously) if you see a recent sale of a same grade lajoie for $400 and it has a small crease or something and yours looks just as good with no crease you could easily ask for several hundred more. These kinds of things just aren't taken into account when you're talking about 520 card lots. And the numbers can really add up. It's just a lot of work and a ton of typing. Which it seems like you already did a good bit of. People will value the time it takes heading to the post office once vs 300 times and a single payment far more and happily take $5000 (or whatever the number may be) less. It's just what suits you, just my thoughts.
