I have a gold (looking) coin I cannot find any info on. The front has an eagle grasping wreath and arrows. Left of the eagle is the letter you and right of the eagle is the letter S. Above the eagle are the dates 1776 and 1976. Below the tail feathers it says BICENTENNIAL. On the back there is a picture of the liberty bell with the date 1776 on the left and 1976 on the right. Above the bell it reads 200 years of liberty. Below the bell it reads United States of America. It is cased in a round plastic protection and seems to be a proof. With it, I have a 1976 penny, nickel, dime and quarter all protected in their individual said containers. I wish I could post a picture, but any help would be greatly appreciated. Thank you.
