Hello, I am new to grading activities and have a question about my 1977 Kennedy proof S coin. The coin is perfect condition and the S mint mark is inverted. How much is a coin like this worth? Thanks

Since this is something not previously reported for 1977-S, it would be hard to say what it's worth. The Cherrypickers' Guide to Rare Die Varieties of U. S. Coins lists a similar 1968-S half dollar at values from $140-225, depending on grade. Checking auction records will assist in determining if those figures are reflective of the actual market.

If you wish to submit your coin for NGC grading and variety attribution, it will be examined to determine whether in fact it is an inverted mintmark. NGC does add new varieties to its roster at the VarietyPlus website when they can be confirmed and they would be something desired by collectors.
