The first G-Files coins appeared in 2008, with several different versions appearing over the years. These coins with a chrome finish and Christmas-inspired colour scheme first appeared in 2015.
The front of each coin shows the Geocaching "G" in the style of the X-Files logo, with a shadowy blow-up of the G's center in the background. The back tells what every geocacher knows: "The Tupperware Is Out There". These are the Christmas versions of the coin using a red and green colour scheme; two use only translucent enamel while on the third the G center on the front and the lettering on the back are done in glow enamel.
