This is a very special coin given only to volunteers of GeoWoodstock4. It is almost the same as a regular GeoWoodstock4 coin, only it has a cut out around the perimeter of the diamond. The owner printed this trackable on tagboard and laminated it so they wouldn't lose the original. I don't blame them! Picked it up from where I dropped it off last so that it could travel, per owner's request. Thanks, MaxB for sharing this with me at MW Geobash '06 as well as the portfolios of your travel bug tours. Sorry it took me so long to get back out there.
