Don't forget that the Deaver is your friend during CC.
This little guy can be bought for 8 dubloons from Little Nippers with those (1 CC-point) dubloons that you get for free from Anchor Management, and he's worth 4 CC-points. I've been getting one any time I need to make change from larger dubloons for training, and have a little pile of the furry guys now. xD
During the current CC accumulation period I made the very important discover that (special) does NOT automatically mean r101. That was quite a moment for me let me tell you!
There's a slew of 4-point (r102-r179) items that you can get from various dailies:-
The older omelettes bar the plain and rotten ones.
The mutant plushies from the Wheel of Misfortune apart from Headless Von Roo.
These are the two I see most often on the money tree so I'm guessing they're the ones won the most frequently?
Weapons from Coltzan other than his basic gem and the Serf Lens
these two fairly often on the Money tree
Battlecards from Cheat
This is the selection I've got from the Tree in the past 15 months
Anything apart from the Yellow Growth on Buried Treasure.
I'm always THRILLED to nab me some rancid old meat from the good ol' MT.
Looking on the list of r102 to r179 items Cheeseroller and Brain Tree quests can net you 4-point items too, and the Deaver isn't the only 4-point Pirate petpet, it's just the best value for money dubloon-wise :3
I bet all of you will have some of these items in your SDBs already.
Also don't forget your shed and closet! Some furniture has high rarity, I know I've ended up with needless multiples of some items in my closet without even realising.
OHH, AND... open any Pawkeet Pinatas that you have! Yes these are a rare - worth 2 points themselves - but what you get out of them is almost guaranteed to be worth it. I opened 13 with a CC points total of 26, and the items within them gave me 82 points! This recommendation comes courtesy of @jaydeed
Hope all this is helpful.
