Just because a grade is listed on a flip, that does not make it accurate. SMS coins should have fully struck details and have something of a polished appearance with high end SMS coins even having a cameo appearance. The problem occurs when you have a high end business strike and an average SMS strike- the coins can look quite similar. There have even been cases of TPGs attributing them wrongly and this can even occur on the current satin finish mint set coins. As far as I know, there are no specific diagnostics to distinguish them. Unfortunately, high end business strike 40% silver halves are quite rare so any half that has a really nice appearance is almost always an SMS coin.
