How much should these coins weigh? I have a range of different weights from 11.0 g to 11.4 g.
Thanks.

So a 1999 weighing 11.0g and a bicentennial weighing 11.4 within the norm?
Thank you Coop.

I would think so but there are silver bicentennials as well that weigh 11.5g plus wear can make it weigh less or playing could make it weigh more.

Correct
that also should have read "Plating" not "playing"

For a clad? I'm not sure where the low weight would come up at on these clad planchets. +/-?

coop, apparently you have a graphic for this.
Quin, it helps if you include the details( mint mark, year, ect) of the coins in question in your original post, you will get more direct answers.

Gincoon43, my original post was a broad question because I had several coins in question, not just one in particular. A 1999 P weighing 11.0 g ( which I found odd because it is not heavily circulated or worn; a '65 @ 11.3 g; '66;@ 11.4 g; many others (various dates and mints) @ 11.2/3; and of course the bicentennial D @ 11.4. I didn't have the weight tollerance at my fingertips. Sometimes it's faster just to ask.
Thank you for the responses.

+/- 13% is a number mentioned before. But I wish I had a complete range of all types to butt to my weight chart.
