So in the Founders Edition there was this "Mission Pass: Gold Ticket" that was pretty unknown in terms of what it did. We now know with the new blog post about about the new feature, Missions Passes! You can read all about it Here
So here is what that specific item does:
"DOUBLE YOUR REWARDS!
All Arks are automatically eligible to earn the rewards listed in the Normal Tier of the Mission Pass, but those who want even more rewards can purchase a MISSION PASS GOLD TICKET and receive rewards from the Normal Tier and Gold Tier for the entirety of the Season! Mission Pass Gold Tickets can be obtained through the Mission Pass interface using Star Gems, with the purchase of a Premium Set through the AC Shop, or by purchase from the Star Gem Shop."
The Gold Tier is the bottom 2 rows here.
Perhaps a JP player or GM could answer, was this on the Japanese version of the game?
This is an entirely new feature.
