Close to perfect, "Finest Known". This is a special uncirculated coin from the Franklin Mint made for Papua New Guinea.
It's not a proof, it's not matte, it's a special uncirculated (U variety indicated by DPL) coin of which only 1,120 were made making this variety exceptionally scarce. Over 42 years the number of these coins available has dwindled making the amount still around significantly lower than mintage amount.
