This should help clarify any confusion with this 1981-S Type 1 and Type 2.
The Type two is a clear wide "S" with a lot of room in the center.
The beginning and end of the "S" looks like it has been flattened
This is different from the 1979 type two where it is much easier to tell. The 1979 Type I is a blob while the Type II is a clear normal "S"
