Gold Price by Karat / Fineness
When buying jewelry or historical coins, gold is frequently alloyed with other metals such as copper, silver, or zinc to enhance its durability. Karat purity directly dictates the melt value of your item:
24K Gold (99.9% Pure): The global standard for investment bullion bars and sovereign coins like the American Buffalo. Trading at full market spot price ($134.55/g).
22K Gold (91.6% Pure): Widely utilized in renowned investment coins like the American Gold Eagle and Crown Sovereign. Valued at approximately $123.25 per gram.
18K Gold (75.0% Pure): The benchmark for high-end designer jewelry, combining rich golden luster with scratch resistance. Valued at approximately $100.91 per gram.
14K Gold (58.3% Pure): The most popular jewelry karat in the United States, offering excellent everyday durability. Valued at approximately $78.44 per gram.
10K Gold (41.7% Pure): The legal minimum standard for jewelry sold as "gold" in the United States. Valued at approximately $56.10 per gram.
How to Calculate the Value of Your Gold
If you have scrap jewelry or physical coins and want to calculate their intrinsic melt value based on today's spot price, use this simple three-step formula:
Weigh your gold in grams using an accurate digital scale.
Determine the purity factor:
24K = 1.0
22K = 0.916
18K = 0.750
14K = 0.583
10K = 0.417
Multiply:
Weight (g) × Purity Factor × Current 24K Gram Price ($134.55)
Example: A 14K gold ring weighing 15 grams:
$15 \times 0.583 \times \$134.55 = \mathbf{\$1,176.60}$ (Melt Value).
Key Drivers Behind Today's Gold Spot Price
Precious metal values do not move at random. The price of gold in the United States is primarily dictated by a combination of macroeconomic indicators:
1. Federal Reserve Interest Rate Policy
Gold bears no nominal yield or dividend. When the Federal Reserve reduces interest rates or signals a dovish monetary policy, yielding assets (like Treasury bonds) become less appealing, driving institutional capital into hard assets like physical gold.
2. The U.S. Dollar Index (DXY)
Because gold is benchmarked and settled globally in U.S. Dollars (XAU/USD), there is an inverse correlation between the greenback and bullion. A weaker dollar makes gold cheaper for foreign buyers, fueling global demand and lifting the spot price.
3. Inflation & Currency Purchasing Power
Historically, gold acts as the ultimate hedge against fiat currency devaluation. When CPI (Consumer Price Index) numbers point to sticky inflation, both retail consumers and sovereign hedge funds accumulate bullion to preserve long-term purchasing power.
4. Central Bank Buying & Geopolitical Risk
In times of geopolitical tension or international trade fragmentation, central banks worldwide aggressively increase their gold reserves to diversify away from counterparty risk.
Spot Price vs. Physical Bullion Premiums
When purchasing physical gold coins or bars from prominent U.S. dealers (such as APMEX, JM Bullion, or SD Bullion), you will notice that the retail price is slightly higher than the spot price quoted above.
This markup is known as the dealer premium, which covers minting costs, secure insured logistics, distribution, and dealer margin.
Gold Bars (1 oz - 1 kg): Typically carry the lowest premiums (usually 1.5% to 3.5% over spot).
Government-Minted Bullion Coins (e.g., American Eagles, Canadian Maples): Command higher premiums (3% to 7% over spot) due to legal tender status, collectibility, and sovereign guarantees.
Frequently Asked Questions (FAQ)
What is the difference between a Troy Ounce and a Regular Ounce?
A standard U.S. ounce (avoirdupois) equals 28.35 grams, whereas precious metals are exclusively measured in Troy Ounces, which weigh 31.1035 grams. Always verify that your scale or dealer is quoting troy ounces.
Is physical gold taxed in the United States?
In the U.S., the IRS classifies physical gold as a "collectible" subject to capital gains tax upon sale. However, many states exempt physical bullion sales from state and local sales tax when purchases exceed specific threshold amounts. Always verify local state tax codes before buying.
Where can I buy physical gold at spot price?
Direct spot purchases are generally reserved for high-volume wholesale transactions. Retail investors can minimize premiums by purchasing larger bar sizes or cast bullion over proof coins.
