  This beer mat or coaster is part of the Budweiser Bud NationPacific Islands collection that was released in 2008. The 9 beer mats andcans from this set include Guam, Chuuk, Palau, Kosrae, Saipan, 
Yap, Tinian & Rota, Majuro, and Pohnpei. The cans were released in eachof the Pacific countries. However, the beer mats or coasters were only releasedin the country featured on the mat. As for the Bud cans, I do know thatthey were released in two sets. The first set arrived in the Marshall Islandsbetween Thanksgiving and Christmas 2008. The five cans in that set were Saipan,Yap, Tinian & Rota, Majuro, and Pohnpei. The second set of cans arrivedafter Christmas and early in 2009. Those four cans were Guam, Chuuk, Palau,and Korsae. The second set is more common than the first, but both sets arevery difficult to come by. Info provided Janaury 2012
