Do blank (empty) Pcgs slabs weigh the same?

Talking about slabs of the same coin/denomination. I'll have a follow up as well.

This theory would go vise-versa when looking at smaller denominations like Half-Dime sizes which I would expect to weigh more.
Do I sense a question coming along the lines of "Can I weigh a coin while it's still in its slab?"

I don't think PCGS makes their own slabs; they buy them.
<< <i>What about these three slabs? If they were coinless would they weigh the same?
Weigh all 3 and see. Assume the coin weighs the same in all 3 slabs so its a constant and can be ignored. Any difference in weight would be due to the slab. Ideally you would like 10 or more of each to get an average weight.
A potential buyer asked if my '82 was copper or zinc cored? The composition changed in '82, but didn't it change "midterm"? The '81 weighs 34.4 grams. The '82 weighs 33.7 grams. The '83 weighs 34.5 grams.

If that's your reason post some good close ups of that coin and I might be able to tell you.
If the coin has any of those little bumps in the plating then it's a zincoln, if not it's copper. You can be sure it's zinc if you see that bumpy finish.

<< <i>Is your reason for weighing just to determine if your 82 cent is copper or zinc?

If the mint struck both types in the same year wouldn't PCGS attribute them accordingly?
The only bus strike cent from 82 that only comes in zinc is the 82-d small date zinc, the others come in both types.
82 LD copper
82 LD zinc
82-D LD zinc
82-D LD copper
82 SD copper
82 SD zinc
82-D SD zinc

that's a true statement Paul. the two piece shell should weigh approximately the same no matter what the coin inside is because they are all identical and made to accomodate the same diameter soft inner ring. all you need to do is look at some PCGS coins of varying denominations to tell that. from that perspective, all slabs holding identical coins should weigh close to the same, probably within .xx grams of each other with the variation being from both the slab and the planchet weight.
i wouldn't think it's a reliable way to determine anything, though.
well, when you spell it out for me it makes sense !
