It all started with a bucket hidden in the woods. 
On May 3, 2000, a GPS enthusiast named Dave Ulmer hid the Original Stash in a remote area outside of Portland, Oregon. He included some trade items, and a log book so any finders could record their visit.  He put the coordinates on a chat board, and encouraged others to go find it. 
The game of geocaching grew from this one bucket! 
To celebrate 25 years of hiders and finders, Groundspeak has brought back a special version of the original stash bucket geocoin! 
This is a 3D design with a working handle.  The lid is attached with magnets, and opens up to reveal the tracking code on the lower side. It is trackable at Geocaching.com with a unique icon. 
Dimensions: Approximately 4 cm tall and 3.5 cm in diameter.
