Coins are interesting, but it is a bit of a hassle to pester everyone in the household if they have a newly minted coin. Another thing is that, for example, in my country the mass of coins is pretty much a random variable: one Lithuanian cent weighs 0. So, for ease and convenience I do this: for small masses, take a syringe everyone has a syringe , put it on the scale and zero it, then take it off and draw, for example, 5 ml of water and put the filled syringe back on the scale and see if it weighs five grams.
For larger masses a measuring cup or a beer glass can be used. Syringes are reliable because their manufacturers cannot screw up the volume marks - it might mean life and death. Measuring cups and beer glasses not always so.
Yes, there are some minerals dissolved in tap water which change its density, but the change is very slight, especially compared to coin wear. That's a good idea using a syringe to measure water to determine correct weight.
We should not use our kitchen measuring spoons or cups because many are very inaccurate. Cook's Illustrated did a test of various brands of measuring spoons and cups and found many to be inaccurate. Mints strive to produce a product that is consistent in diameter, thickness, and material used.

These coins weighed 3. In , the mint produced half of the pennies with the solid copper composition and half of the pennies with the copper-plated zinc composition.
In , Congress dictated that the United States Mint changed the composition of the penny to a core of pure steel plated with zinc. This change in composition was intended to save copper for the manufacturing of munitions to be used in World War II.
These steel pennies weigh 2. These steel cents quickly started to rust and deteriorated. In , Congress reversed its decision, and the composition returned to the copper and zinc alloy. Since the United States Mint began producing nickels in , the specifications remain fairly constant. The five-cent coin is composed of 75 percent copper and 25 percent nickel.
Nickels produced between and had a slightly smaller diameter of Since nickels produced in the United States are composed mainly of copper, Congress once again intervened to change the composition of the coin to save copper for the manufacture of munitions to fight the war in Europe. From until , five-cent coins were composed of 56 percent copper, 35 percent silver, and 9 percent manganese. These coins are easily distinguishable by the large mint mark located above the dome of Monticello on the reverse.
Since , all United States dimes have outer layers of 75 percent copper and 25 percent nickel clad to a core of pure copper. A cent coin weighs 2. Roosevelt dimes dated before were composed of 90 percent silver and 10 percent copper and weighed 2. All cent coins manufactured since have outer layers of 75 percent copper and 25 percent nickel bonded to a core of pure copper. They weigh 5. How much flour will be needed for four samosas?
