So, this clad Kennedy half dollar is a bit underweight but I think is too heavy to be on quarter stock. If it is not the correct thickness, it is pretty close to normal thickness, it is the correct diameter, and sounds like silver even though copper is evident on the edge. Any ideas why it is so underweight? Thank you in advance. --Curtis   |

Weird, 9.8g, but supposed to weigh 11.50
Interesting, no idea. Wrong planchet?

What do other halves weigh on your scale ? What made you want weigh this half ?

Other halves way correctly on this scale; I weighed a different half after taking this picture and it weighed OK.
When I was looking through the roll this one looked like a normal half on the edge, but sounded like silver, so I weighed it.

This might be on SBA stock but not on an SBA Planchet - hard to say |

It seems unlikely to be SBA given that you have a full and centered strike. SBA planchet is quite a bit smaller. Could it be counterfeit? You say the metal seems off, too. Would be a weird one to fake, but stranger things have happened. Edited by tkbslc

Posssibly struck on SBA metal stock, not to be confused with being struck on an SBA planchet. |

<Posssibly struck on SBA metal stock, not to be confused with being struck on an SBA planchet.> biokemist6, I agree with you. Will post if I figure anything else out. Thank you all for your input. Take care. --Curtis |

Too light to be on SBA stock. Half on SBA stock would weigh 10.8 grams. On minimum tolerance thickness SBA stock they would weigh 10.4 grams. Half dollar on quarter stock would weigh 9.03 grams. If on quarter stock rolled to the thickness that would produce quarters at the maximum of the tolerance range they would weigh 9.39 grams. Edited by Conder101

Nothing wrong with the math, you have to consider the tolerance range for the strip thickness. 9.03 grams would be for strip that produced exact weight quarters. As I mentioned above strip that would produce quarters at the maximum tolerance weight would make halves that weigh 9.39 grams. Strip that would produce quarters at the minimum tolerance weight would make half dollars that weighed 8.67 grams.
So because of mint tolerances, a half dollar struck on quarter stock can weigh anywhere from 8.67 grams to 9.39 grams.

I see.
Any idea what it is, then?
