Collections from buildings ???? Upcoming content

These are memorabilia or a collection of objects like the character collections once you complete a set you earn money and XP. Each of these items could be found randomly after doing jobs( the odds are very low like findings donut cleaning) or cost 1 donut each. This is part of the unreleased content that was planned but never made it in the game it doesn't look like there are plans to release it anytime soon.
