Thanks for the link. I've heard of them being graded incorrectly. The 7's position relative to the 9 & 0 and the 9's tail indicate a large date to me. However, the 7 does lack that tell-tale "ridge" of a large date. (from:
http://www.thecentproject.com/sort1970.phpI think by this measure (The easiest way to tell the difference is to look at the 9. If the loop of the 9 bends sharply toward the 7, it
is a small date. If the loop of the 9 is angled toward the top of the mintmark, it is a large date. The nine
in the small date is also "wider" looking than the 9 in the large date.)...it's a large date. Just my two cents.
