1967 Kennedy Half Dollar 12.3 Grams

Ok, how about a shot of the coin's edge? then another image with a normal coin's edge laid on top of this one, that'll be helpful.

Place a U.S. quarter on your scale and post a pic. Also post of pic of the entire reverse of the coin.

Well, thank you for the pictures of the edge. If you look closely, you can see a fine line intersecting the middle of the edge That line is from the Copper/Silver core (mostly copper) and you can also see the silver/Copper (mostly silver) Cladding over that. This tells me that this is a 40% silver half dollar. If it were the 90% silver version from 1964, you would not see that line down the middle.

What I think you have is a slightly rolled thick planchet. I also would recommend that you get an XRF test done to verify that.

What a XRF TEST?
And does that bring a premium ?
Could be maybe on a foreign planchet?

I appreciate all the feed back and help

Thanks

When you originally posted that was my thought (foreign planchet) as the only possibility.

I believe the U.S. Mint was striking 90% silver Pesos for the Philippines in 1967 but they were 38.1 mm in diameter. The 50 Centavos pieces were 27 mm in diameter and contained no precious metal.

You could also try a specific gravity test in addition to the XRF. Any decent size jewelry store or coin shop should have and XRF.

11.9 grams was the max weight for 1967 halves. My guess is you have an out of spec coin that is 40% silver. Your edge photos confirm that. That far out of spec is unusual and should bring a decent premium as a mint error.

Should I send this coin to PGCS etc?

Not a wise investment since the costs of TPG will exceed your coin's premium. After posting the edge picture it clearly shows Copper therfor it is not Struck on a Silver planchet.
I agree with DearBorn on the possibility of being a thick rolled planchet since you are confident your scale is calibrated correctly if so it will fetch a premium above the face value but not enogh to justify the TPG costs, as always the final decission is in the Eye hands of the beholder.
