The mint has had a problem with consistently making sure all the mint set coins have their satin finish ever since they started them in 2005 The "Satin Finish" seems to be rather delicate on the dies and it quickly deteriorates back down to a normal business strike finish. However the mint set coin ARE struck much better than the typical business strike. For that reason many people search the mint sets for those coins that DON'T have the satin finish and submit them to the grading services trying to pass them off as top quality business strikes (and often succeeding.) Why? Because due to their good strikes a MS-69 SMS coin is fairly common. But a MS-69 BUSINESS strike is not and will bring a high price. A MS-68 non-satin finish SMS coin, if the graders don't catch it, will come back as a MS-69 business strike.
