I'm actually surprised that you found that much variation. Coins are supposed to be held to pretty exact tolerances.

What may be the case, though, is that given that coin compositions have changed over time, you might very well have gotten some older coins with different cladding or blank standards.

I think it would be more indicative if you were to weigh coins from the same time frame.

That said, just about anything can become a check weight, including a coin, a metal nut, etc., as long as you weigh it carefully to establish its weight and hang on to it.
