As NSS-52 notes the date position could be different between dies. There are a number of known varieties within the type 2 obverse and type 2 reverse on the 1877 S as Breen identified 5 different varieties.
One of the problems I find with Trade dollars and detecting counterfeits is the lack of documentation available on the different Trade dollar varieties within the type 1 & 2 obverse and type 1 & 2 reverse.
