I feel like both major TPGs are inconsistent on the SMS coins. Over the decades, what they call them and how they designate them has varied - and they are even inconsistent with their own policies. This is a classic case where the collector must grade the coin for themselves, and buy the coin, not the holder.
Interesting. I didn't bother to check census. I just knew Ebay had them graded per NGC. I think a previous post already mentioned that PCGS didn't have any SMS graded with a full torch designation.
