Ron Guth: The 1947 Dime is very common in all grades up to, and including, MS-66. MS-67 examples are scarce but can be found for a price. None have been graded finer by PCGS (as of August 2011).
Full Band (or Full Torch) examples are much scarcer and they follow the same grade distribution as the non-Full Band examples. The finest FB exampl;e certified by PCGS is a single MS67+FB.
