This years coin is fancy-schmancy featuring a spinning, translucent, stained glass effect Luna Moth. The coin is a large 60mm across with a polished nickel finish. Online pre-orders are discounted and available through Oct 1, 2018 (or until sold out). There are only 80 of these being minted. If there are any geocoins remaining, they will be available for purchase at the event.
There is a special edition of this years coin plated in a gold finish that can be obtained by winning one of the many contests throughout the weekend, purchasing a sponsorship, or finding one of the few that escaped into the wild, oh yea....there will be some in the wild this year.
