For your consideration, here is a 1976 Lewis County, Washington State Bicentennial Token. It has very little wear on it. It has a diameter of just under 1 5/8 inches. Item pictured is the actual item up for sale and comes from a non-smoking household. (155.98c-.4ob)

It has a design with famous Lewis County sites on one side. The reverse has printed on it, in the middle:

DEDICATED TO THE NATIVE AMERICANS AND THE PIONEERS OF LEWIS, THE MOTHER COUNTY OF WASHINGTON, ESTABLISHED BY AN ACT OF THE OREGON TERRITORIAL GOVERNMENT DECEMBER 19, 1845.
