This coin was minted by the Poarch Creek Indian Nation. It is in a plastic airtight container, but has a hint of toning at 3:00 on the obverse. I would guess the grade in the MS65-69 range.
The obverse shows a Creek Indian dancing to the right (performing a Skydancer ceremony), while wearing traditional tail feathers, a head dress, and leggings. He is advancing on a seal of the Poarch tribe of the Creek nation. The legend reads “Creek Nation of Indians” from 8:00 clockwise to 4:00. The denomination “One Dollar” is at the bottom from 7:00 clockwise to 5:00. There is a ring of dots separating the legends from the iconography of the coin.
The reverse shows the busts of five men (1 in traditional garb, and 4 in suits). At 12:00 is the legend “Sovereign Nation” and at 6:00 is the legend “1984 – 2004” separated by the seal of the Poarch Creek Nation.
