The 1962 Seattle World's Fair PCGS Certified Genuine LARGE US Mint produced 90% Silver Medal is a historic and collectible piece from the United States. This medal commemorates the 1962 Seattle World's Fair and is made of 90% silver, weighing 4.94 oz. It serves as a unique and valuable memento of this special event, showcasing the theme of World's Fairs and the rich history of fairs and expositions in the United States.  Total pure silver content of 4.4 oz. valued at $300 based on a $68 per oz silver price.  It is slightly greater than 2.5 inches in diameter (65 mm).  I sent this medal to PCGS to be graded, but it was scratched in the process and could not be graded.  See photos of the (minor) scratch.  The medal is of a high MS condition and was never out of its original mint packaging until it was sent in for grading.
