At one point, I worked out that US dimes, quarters, and half dollars all weigh $20/lb (iirc), which made the task of counting my accumulated change a lot easier.

https://en.wikipedia.org/wiki/Coins_of_the_United_States_dol... confirms that, and shows it works for dollar coins, too (I’m using the weights in grains because that makes the comparison easier; a pound is exactly 7,000 grains)

Dime: 35 gr

Quarter: 87.5 gr

Half-dollar: 175 gr

Dollar: 350 gr

Nickel is ~5 grams. Dollar bill is ~1 gram.

I like how easy it is to remember nickel == 5 g.

The "ten US nickles is always 50g" mantra has helped me detect several defective scales (whether intentional or not, I want accuracy).
