This is a really dumb question but I don't know the answer so I'm going to ask anyway. I have this 1960 dime, graded by PCGS as a MS66. The obverse of the dime looks to be aligned perfectly in the slab, put when you flip it over the reverse is slightly but noticeably rotated. Is this a common thing? What causes it? Does it affect the value of the coin positively or negatively? Here are the seller's pics. You can see how the reverse of the coin is not even with the obverse.
That is almost microscopic it is so small. If it is 15 degrees (I believe) or more, the graders will call it an error (if you pay them to). So less than that won't be worth more. The more the rotation, the bigger the premium. This one is not worth any extra.
I know you were just kidding bugo, but in actuality there were the standard silver qurters from 1932 to 1964 at 6.25 grams and .900 silver content. There were also silver proof quarters issued from 1965 to date with same consistancies as the pre-1965's. We could also include the 1976 Bicentennial that consist of a outer layer of .800 silver with an inner core of .0739 oz of pure silver. And at last we now have the 5 oz .999 fine silver quarters
Not entirely true Dave. 90% silver didn't appear back on the scene ( after '64) until '92 and then in the form of proof coinage.
