I finally decided to look closer at how collectibles are crafted or gathered and finally managed to figure out how to do it.
For a long time I never gave it much thought or effort to get collectibles and yesterday I decided to try.
I noticed that a lot of unique items and ingredients were appearing with no use to them in crafting.
It occured to me that these could be made into collectibles.
I also noticed that it is very easy to check where you can take the collectibles by clicking the timers button and clicking the various collectible related timer such as custom deliveries and supply missions.
So now when out gathering or running for a rare timed node I will look closer at the items available and make the best collectible I can gather and actually turn it in for scripts.
