WHAT IS A TROY OUNCE?

Coin Trivia Only At Oceanside Coin Center

THERE ARE 2 KINDS OF OUNCES---TROY AND AVOIRDUPOIS

(FOOD OUNCE)

THE AVOIRDUPOIS OUNCE CONTAINS 28.35 GRAMS.  IT IS THE STANDARD UNIT OF MEASUREMENT FOR FOOD AND OTHER BULK ITEMS.

THE TROY OUNCE CONTAINS 31.1 GRAMS.  IT IS THE STANDARD FOR

ALL PRECIOUS METALS (GOLD, SILVER, PLATINUM, PALLADIUM, ETC., AND FOR THE SPOT PRICES YOU CAN GET DAILY ON THE INTERNET.  THAT SPOT PRICE IS FOR ONE TROY OUNCE OF THE “PURE” (.999) METAL.

Coins that are circulated typically do not contain either pure metal (.999)

or weights that are troy ounces or fractions of a troy oz.

   Bullion coins may not be .999 but they will generally have enough 

Of the metal to equal the troy weight stated  on the coin.

EX: The American gold eagle (1oz) weighs 33.933 grams and contains

31.1 grams of .999 gold.  After the alloy metal is added you have 33.933

Ounces of .916 (22karat) gold.

UPDATE:  I FOUND THE TWO ROOSEVELT DIMES I NEEDED AFTER LOOKING THROUGH  22 TUBES OF DIMES—THEY WERE BOTH IN THE SAME TUBE!
