Missed the live stream because I’m terrible at time differences it seems. What an interesting little token - a sun, moon phases, and a few constellations. Also, the number on the back when Googled (which might be too easy?) leads to a book called “In Search of Schrodinger’s Cat - Quantum Physics and Reality” as 0553341030 is its ISBN10 number - kind of fits with the theme of multiple realities though.
EDIT: the front symbol is a symbol for the Guide
