I found this dime in my change from Walmart
the other day and thought that it was simply old and worn from circulation. When I took a closer look at it planning to check the date to see how long it had been around I discovered that it was half the thickness of a normal dime and what I thought was wear actually could be a result of the planchet being thin and the die not hitting as hard as it should. So I did some comparing of the dime to some foreign coin that I have and discovered that it was about the same thickness of a Canadian coin. I also found that both coins weigh 2.08 g. Is this possible as the dime was minted in Philadelphia? Also would the value of that type of error be worth spending the money to have it graded?
