Of course. The full split bands indicate a well-struck coin. On most Mercury dimes the bands on the reverse of the coin are rather poorly struck, even on an uncirculated coin. On some though, the coin is well struck and there are full split bands. While there are some mints and years with better quality strikes than others, it is entirely possible to see uncirculated Mercury dimes in the same grade, year and mintmark and some have full split bands and others lack that designation.
