Mint set error?

CkTex

I recently purchased a 1971 unopened US mint set. As soon as it arrived I felt like a child on Christmas morning. I carefully opened it and looked over them. I noticed not only the high grading potential but also I had a Denver mint dime in a Philly set. I know the dime itself would only be worth what it graded at but in complete unopened package set would it be more valuable?

There have been a few mentions on the main Forum of such packaging errors. There isn't a real concensus on whether or not there is much or any added value. Unless there are very high grade coins in your set, it might be best to keep it as a curiosity.
