Paul - 1972 Kennedy Half weighs 10.37 grams should weigh 11.34

#1 Unread post by mystrey9 » Sat Feb 29, 2020 11:02 am

I have calibrated my scales and reweighed this coon many times. All my other Kennedy Halves weigh correctly and I weigh this again and it weighs 10.37 grams. I read that the lowest tolerance is 10.8 and this weighs less then that. Any help would be greatly appreciated.
Thank you

Can you?:

Sandwich this coin between 2 of your 'normal' coins, use something to stand them up on edge, snap a picture and post here…

TY…

It's obviously not "Thinner" than a normal coin, whereas it would have been struck from 'rolled thin stock'....
mmmmmmmmmmmmm, I'm sort of baffled here,.............

I do see a slight weakness in the strike on the reverse at K12 – K1, but that would not make up for the difference in weight here.

Is it worth sending to PCGS and have them figure out the error?

May I ask what you're using to calibrate your scale?

There are different ways that it said and I have tried them. One was to hold down the Tare button until everything goes back to 0. And the other way is to use a coin. But every time I weigh it, it still comes out the same weight. And my other Kennedy Halves still weigh their correct weight.

I also tried my postal scale and it came up 10 grams.

Did your scale include a set of 2 different specific weights..... That are used to "Calibrate" the unit?

....... if you do not have these 2 different standardized weights, you will need to find a set to properly calibrate the scale.
