Vintage Alaskan Ivory Tie or Scarf Clip with Scrimshaw Walrus and Gold Nugget

Vintage Ivory Tie or Scarf Clip with Scrimshaw Walrus and Gold Nugget. The gold nugget has not been authenticated, but it does go all the way through the piece as shown in the pictures. Overall length is approximately 2-1/2 inches long and the ivory portion is approximately 1 inch long and 3/4 inches wide. I don't believe this was ever used and is in excellent condition.
