Troy weight is a system of units of mass originated in 15th-century. One troy ounce contains 2.75 grams more than a regular ounce. If you were to place it on a regular scale it would be approximately 10% heavier than the standard unit of measure. To be exact, one regular ounce is 28.35 grams, while a troy ounce is 31.1 grams. A headline like this stuck to forum can be a welcome introduction. Some other tips may help confusion for example, 1/10 coins, filled, clad, plated or 99.99 vs 99.999 and any other terms defining the actual content of an object. I personally would like to see something like this in forum introductions.
