Technical Breakdown: Physics, Metallurgy & Die Diagnostics
Precious metals stacking and bullion trading operate across several competing international weight standards. While wholesale spot markets quote exclusively in Troy Ounces ($/oz t), physical fabrication, jewelry scrapping, and international markets trade in grams, tolas, baht, taels, and pennyweights.
Wnet_troy_oz = [ Mgross_units × Cunit_to_grams × Ffineness ] / 31.1034768
Standard Conversion Multipliers (Grams per unit):
• 1 Troy Ounce (oz t) = 31.1034768 grams
• 1 Avoirdupois Ounce (oz) = 28.3495231 grams (A troy ounce is ~9.7% heavier!)
• 1 Indian Tola = 11.6638038 grams (Traditional Indian subcontinent standard)
• 1 Thai Baht = 15.244 grams (Thai gold bullion standard, 96.5% purity)
• 1 Chinese Tael = 37.429 grams (Hong Kong / East Asian market standard).
Net Pure Silver = Face Value ($) × 0.715 Troy Ounces
Although an uncirculated $1.00 face of pre-1965 silver contains 0.7234 troy ounces when struck, the bullion trade universally deducts 0.0084 oz per dollar (~1.16%) to account for average commercial friction wear.

Frequently Asked Questions
What is the difference between a Troy Ounce and a standard Avoirdupois Ounce?
A troy ounce (31.1035 grams) is approximately 9.7% heavier than a standard everyday avoirdupois ounce (28.3495 grams). All precious metals (gold, silver, platinum, palladium) are quoted and traded exclusively in troy ounces worldwide.
What does '90% Junk Silver' mean?
Junk silver refers to pre-1965 circulating US dimes, quarters, and half dollars composed of 90% silver and 10% copper. It is called 'junk' because the coins possess no numismatic collector premium, trading strictly for their intrinsic silver bullion melt value.
Why does a 1 oz Gold American Eagle weigh more than 1 troy ounce?
The American Gold Eagle and South African Krugerrand are struck in 22-karat gold (91.67% gold, 5.33% copper, 3% silver for wear resistance). To ensure the coin contains a FULL 1.000 troy ounce (31.1035g) of pure gold, the gross weight of the coin is 33.93 grams.
What is an Indian Tola?
A tola is a traditional South Asian unit of mass standardized during British rule at exactly 180 grains or 11.6638 grams. A standard '10 Tola TT Bar' contains 116.64 grams (3.75 troy ounces) of 999 fine gold.
How do I calculate the gold value in 14k scrap jewelry?
14-karat gold is 14/24 parts gold, or 58.33% purity. Multiply the total gross weight in grams by 0.5833 to get pure gold grams, divide by 31.1035 to get troy ounces, and multiply by current spot gold price.
What is Sterling Silver?
Sterling silver is an alloy consisting of 92.5% pure silver and 7.5% copper. It is stamped '925' or 'Sterling' and is widely used for tableware, decorative objects, and world coinage like British pre-1920 crowns and shillings.
How do premiums affect physical bullion purchases?
Bullion dealers charge a premium above the spot melt price to cover minting, shipping, and dealer profit. Premiums range from 2% to 4% on 100-oz silver bars or 1-oz gold bars, up to 15% to 25% on 1-oz American Silver Eagles.
