Rolled on thin or thick coil stock will be worth less than the grading fees and not much collector interest. If it was struck on an incorrect planchet, one that weighed the same, you would need to have the coin examined by the mint or one of the grading services. Images will not help with this.

Paul, not sure what it should be for the 72 half. I weighed both my 72 philly and 72 Denver. The D came out at 11.37 and the philly 11.35.

PS. I used a 20gr and 50gr calibration weights.

if he has weighted various other Kennedys and they were within normal Kennedy weight's, I would say the scale is fine. Now I found a magic coin Kennedy a couple of days ago and it weighed light. Drop the coin and drop other Kennedy's, do they sound the same? I don't know enough about Kennedy and the mint whether or not they may have been experimenting with different alloys in 1972, but there is that possibility. Counterfiet coin?
