As I've been sorting through the collection put together by my uncle and father long ago, I've come across a baggie with a bunch of blanks/planchets.
I was pretty confident that they are not slugs or anything else based on their diameters being consistently shy of a finished coin and the silver coins having some toning to them but I still decided to get a pocket scale, calibrate it and do some weighing.
Here's are the results of the Specs vs Actual:
Silver Quarter - 6.25g Spec vs 6.28g, 6.18g
Silver Dime - 2.50g Spec vs 2.57g, 2.52g, 2.51g, 2.50g, 2.50g
Nickel - 5.00g Spec vs 4.97g, 4.89g, 4.87g
Cent - 3.11g Spec vs 3.13g, 3.10g, 3.02g, 3.02g
These variances are within the Mint's tolerances, right? Up to ten hundredths of a gram seems pretty miniscule.

A general rule-of-thumb would be +/-0.1 grams for an uncirculated coin/planchet although the actual tolerance for a given denomination or series may be slightly larger.

That would also depend on when the blanks/planchets were created. I believe tolerance in the past was greater than it is today.

Seems like all are within the proper weight range.
What do you have ? Blanks or planchets.
Blanks carry a little better premium over planchets.
Quarters and half's are pretty scarce out there.
Followed by nickels and dimes.

2 Silver Quarters
5 Silver Dimes
3 Nickels
4 Copper Cents
I'm pretty sure they're all Type 2 with the raised rim. The cents and nickels seem flatter but I can still feel a slight rise.

I also have a copper blank that I need to throw into the identification section once I get my calipers out. It is a bit larger than our cent and weighs in at 3.48g.

All the weights listed in the first post are within tolerance.
Quarters 6.25 +/- .194 grams
Dimes 2.5 +/- .097 grams
nickels 5 +/- .194 grams
cents 3.11 +/- .13 grams

The thickness of the planchets are the variables in planchet weight. They would be the same diameters.
