1971 Kennedy Half dollar question

Hello everyone, First of all Thank you for accepting me to join this site. My question is understanding tolerance for a coin, I have a 1971 D Kennedy Half dollar that weighs 11.4 grams so now how would you determine which way to go? It's in between the normal weight which is 11.3 grams which then it would be a minus tolerance right? Or would I go towards the plus which would make the weight of the coin 5 grams? I don't understand your thoughts please. Thank you

    Not sure I understand your question but maybe this will help

    The specification for Clad Kennedy Half dollars is 11.34 gms +/- 0.454 grams. Anything between 10.886 and 11.794 gms is considered normal and yours falls well within that range.

    Also, don't forget that your scale only has a resolution to 0.1 gms so it could be anywhere from 11.35 - 11.44 and still read 11.4 (assuming it's calibrated and leveled)
