In the absence of certified check weights, you can use US coins to verify accuracy on your powder scale. Each nickel weighs 5 grams. That converts to 77.16 grains.
Pennies weigh 2.5 grams, or 38.58 grains.
Easy calculations, and you can zero your scale very accuratly using coins. I would recommend the newest, best condition ones you can find.
My RCBS 5-0-5 scale weighs one nickel at exactly 77 grains, and two nickles at 155.1 grains, which is only .78 grain off true weight. Close enough I think.
