No "S" mint, silver plated will pass tissue test and a plated coin will weigh heavier than a like coin that is not plated. Why is the "hold" button pushed on the scale? |

All I see is a coin under a tissue. You need a couple normal cupronickel coins and a silver coin under that tissue for comparison.
A clad half is 11.34g. A 40% silver half is 11.5g. But if you added a small amount of plating to an 11.34g clad half, it could easily add 0.16g to reach 11.5g.
If you are dead set on grading the coin, consider ANACS. It would be much cheaper than PCGS.

While the weight and appearance are consistent with a silver planchet coin, they are more likely explained by silver plating. My researches indicate that there are no known examples of Philly-minted silver Kennedy half dollars. If you feel that strongly that your coin is the only known example, by all means send it in for authentication. Please report back with the results.

Halves minted at the San Francisco Mint (S) were 40% but the rim edge is silver looking. Probably a plated coin originally minted at Philadelphia. Philly did strike six, if I remember correctly, of each half and dollar on 40% planchets dated 1976. I can't see the edge well or many surfaces but I don't see anything to rule out the possibility it's genuine despite remarkably long odds. It might look plated in hand but some 40% do tone similarly. Don't forget as well that some 40% half dollars are very hard to see the 100 fine center. Better pictures might go a long way toward being sure it's plated. An angle with diffuse light of the edge with the rim. When the color gradient is consistent across this the coin is plated. Time don't fly, it bounds and leaps.

As stated before, it's obviously been plated. It would be a huge waste of money to get it slabbed. It's not silver as Marv said. Do what you want, but you're going to learn the hard way.

If it was a Denver coin, I'd say send it to PCGS for verification. Reason being SF mint routinely sent reject proof planchets to Denver for business strike coining. That is why 1974-D Ike silver clad dollars and 1977-D silver clad quarters, halves and dollars exist.
Being a Philly coin, I definitely think it's plated. I have never heard of planchets going from SF to Philly.
