One of the better joke chips was the April Fool's 1997 from the Fiesta Rancho, North Las Vegas, CG074776. Imagine, Martians trying to invade New Jersey?!!

More serious, the current chips from Stars Casino in Tracy, CA. Big star twinkling with two smaller ones peeking over its shoulders. The cardroom itself, however, is not particularly space-themed other than the challenging "space" between the card tables.
