It is indeed a gas station giveaway - the 1968-69 Shell Mr. President's Game. You may see some aluminum versions - those were the game pieces. The brass tokens were part of one of the prizes: a coin board with all the Presidents up to LBJ. The filled in hole at the top was - I assume - in case there was a different President come Jan 1969 and there was. I believe they made Nixon tokens, once the game started, and you could pop out the cardboard plug and put him at the top.
