The Mint Set coins will not be the same as the business strikes- they will be composed of the original bronze alloy(95Cu/3Zn/2Sn). However, that has created another problem which has delayed the release of the Mint Sets. The Mint has not worked with that particular alloy in a long time(pre-WWII) and they have been dealing with tarnishing issues and have been working on anti-tarnish treatments for the cents. Even if they were not in the bronze alloy, they would probably be of a better quality than the business strikes as have all satin finish Mint Set coins since 2005. They typically grade 2-3 points higher than the best business strikes due to different handling and striking techniques.
