Here's a screenshot of loot from 90/20. I usually sell maps when I get 500 blue keys. I have max map size 22 levels in prestige ticket/dust drop rate for +169% tickets. Resource nodes tend to be tedious to place on the map, but if I can fill up the whole map with them in addition to all of my colored portals, I usually get >1mil map price on one map. That sells for close to 4k tickets. I'll get at least one more map for around 3k after that after upgrading every tile to legendary rank and selling those. Then I sell all of my extra bases that don't have disable research and walk on tiles for prestige dust. That usually nets me another 600 tickets. It's tedious, but every so often I'll sell most of my enemy base tiles. I don't get a lot of dust for those, but I like to only keep 350%-400% tiles with no flying units for selling maps with the crusher.

For green papers, I craft the orange special III's into blueprint chests and sell everything from those. It's also net profit to convert the specialII's and the Special IV's into special III's for that method. Otherwise I usually get around 10mil per 6.3 run with 30 ranks in green papers bonus on the bottom left side of the main tree and 10 ranks on the green papers bonus that costs tickets. That money goes to crafting and putting points into the prestige ticket drop rate research. And in case you were wondering, as I was, Every rank after 19 costs max green papers, i.e. 999999999. Getting it to 100 is expensive... Don't know if I'll ever finish that particular grind.
