Wow, very interesting read. Very educational also. My quarter weighs exactly 4.2 grams. So is it safe to say that it was struck on a dime planchet? I think that I will get it slabbed.
Yes Marve65, the 1/2 did come out of a SMS set but it is hit or miss on how PCGS grades the coins. I have submitted as SMS and it comes back MS and vice versa. I'm not sure but I suspect that the original owners have taken out some coins and replaced them with other coins.
