Silver coins are measured by weight in grams.
Newtons
A newton - or a millinewton.
Coins are not cylinders. The rim of the coin is sometimes raised, as well there are depressions and peaks from the design of the coin. You should use a specific gravity test with water and a scale.
Lay a ruler across the coin and make sure it measures from one edge through the center to the other edge. Read the diameter from the ruler.
lemon juice will clean a coin great. But don't use it if the coin is valuable or collectible, that will lower the value. hope this helps. Brian
No, you do not clean coins. Cleaning coins will only damage their value. If you feel you must clean a coin, take it to a coin dealer and see what he recommends to clean the coin, however, they will recommend you not to clean it. Coins potentially worth hundreds of dollars have been brought down to selling them for scrap because people have cleaned them! Do not clean coins!
You can clean a silver coin by using a mild soap and warm water. Gently scrub the coin with a soft-bristled toothbrush to remove any dirt or residue. Avoid using harsh chemicals or abrasive materials that could damage the coin's surface.

If you have a coin of any value - DO NOT CLEAN YOUR COIN. All cleaning products are either acidic or abrasive and will damage or destroy the finish of the coin. If you have a coin that is of no particular value and you just want it to look shiny, use a jewelery cleaner or a soft drink.

Grams or milligrams would be appropriate units to measure the weight of a five peso coin.
Micrometer.

In water, it just gets clean.
Well, honey, you grab yourself a trusty ol' caliper, the kind that can measure thickness down to the millimeter. Gently place that coin between the jaws of the caliper and give it a little squeeze to get an accurate reading. Just make sure you don't go all Hulk on it and squish the poor thing flat!
Never clean old coins, pennies, nickels, dimes, etc... Coin collectors want the natural patina. If the pennies have dirt on them then soak them in water to remove the dirt. But don't use any detergents. Detergents can damage the surface of the coin and leave pitting lowering the value of the coin. Also do not rub the coins together to loosen the dirt, this can scratch and wear the coins and lower the value. Coins (US Coins) will be worth face value to a non-coin collector, but if you plan to collect coins or just clean them to sell as collector pieces, then don't clean them.
