hello can someone please help me out with this 1969 uncirculated set?!? From my understanding the Denver mint package (red) all the coins are stamped with a D mint mark which mine are and the Philadelphia mint package (blue) has
no mint marks on the quarter penny and dime but also includes the San Francisco minted nickel and Penny that are stamped with an S mint mark Right? Well in my Philadelphia package I have the S mint mark nickel and the additional penny, but there is no S mint mark on the additional penny that's included in the Philadelphia package . I'm just trying to figure out if its something I should hold on to or is our just nothing? PLEASE SOMEONE HELP ME! Basically I am trying to find out if I have a 1969 S that's missing. It's mint mark somehow and if so, could I prove that by sending in the sealed unopened uncirculated mint set to a grading company or do I just have two Philadelphia pennies in there for some reason and if that's the case does that make the uncirculated set an error error set somehow? I would just like some advice as I am not an expert.
