Practical Guidance for Anyone Sorting Through Old Jewelry, Coins, or Silverware
\n\n
Many people inherit or discover unwanted gold and silver items—such as broken jewelry, outdated chains, dental gold, sterling flatware, or coins—that they no longer use. Whether you want to sell, recycle, or simply understand what you own, the first step to knowing the value is to weigh these items accurately. This guide walks you through how to weigh gold and silver at home, why accuracy matters, and how to prepare your information for a clear valuation and secure sale.
\n\n
Why Accurate Weighing Matters
\n
The value of precious metal items is determined largely by their purity (karat or fineness) and their weight. Because pricing is usually quoted per gram, even a small weighing error can affect your estimated payout. For example, a one-gram difference in 14K gold could mean several dollars gained or lost.
\n\n
Tools You Need
\n
\n
Pocket gram scale: Look for one that measures in grams with at least 0.1-gram accuracy. Many affordable options are available.
\n
Magnifying loupe or lighted magnifier: Useful for spotting karat stamps, hallmarks, or purity numbers (e.g., 10K, 14K, 18K, 22K, 24K for gold; 925, sterling, or .999 for silver).
\n
Small containers or zip bags: For separating items by karat or material.
\n
Notebook or digital spreadsheet: To record weights and notes. GavelBase or other record tools can help if you want to organize more thoroughly.
\n
\n\n
Step-by-Step: How to Weigh Your Gold and Silver
\n
\n
Check purity stamps first: Identify whether the piece is marked 10K, 14K, 18K, 22K, or 24K gold. For silver, look for 925, \"Sterling,\" or other fineness marks. Items without marks may need professional testing later.
\n
Remove non-metal components (when safe): Take off clasps, stones, or other obvious non-gold/silver parts if they can be removed without damaging the item. If unsure, leave them intact.
\n
Turn on the scale and calibrate: Place the scale on a level, stable surface away from vibration. Zero it before weighing.
\n
Weigh each group by karat or fineness: For example, place all 14K items together, note their combined weight in grams, then repeat for 10K, 18K, sterling silver, etc.
\n
Record the weights: Write down the value next to each category, e.g., “14K gold: 12.4 g; Sterling silver: 45.6 g.”
\n
\n\n
Understanding Melt Value vs. Offer Value
\n
Once you have weights, you can calculate an estimated melt value using current gold and silver prices. Melt value = (weight in grams) × (purity percentage) × (spot price per gram). However, buyers often offer slightly less than melt because they must refine, process, and handle risk. Likewise, jewelry with gemstones may sometimes bring more than melt if intact, but broken pieces usually sell for metal content.
\n\n
Example Table
\n\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n
Material | Purity | Weight (g) | Melt % |
|---|---|---|---|
Gold Ring | 14K | 5.6 g | 58.5% |
Silver Spoon | Sterling 925 | 32.5 g | 92.5% |
\n\n
Special Case: Dental Gold
\n
Dental crowns, inlays, and bridges are often gold alloys, usually between 10K and 22K. These may contain porcelain or steel supports. If handling loose pieces, separate visible non-gold material, but do not attempt to break apart embedded metals on your own—just place the entire piece in a small sealed bag. Record its weight and label it as “Dental gold (mixed).”
\n\n
Preparing for a Mail-In Appraisal or Quote
\n
Once you have your weights recorded, you can request a free mail-in kit or appraisal kit from a buyer. Typically, this includes a secure, tracked, and insured envelope or box. Reputable companies such as International Gold & Silver provide this so you can ship safely with chain of custody intact. Before sending:
\n
\n
Photograph each group of items and note their weight.
\n
Keep separate bags labeled by karat or metal type.
\n
Use bubble wrap or padded pouches for small pieces.
\n
Ship via a service with tracking and consider USPS Registered Mail with insurance for high-value shipments.
\n
\n\n
What to Expect During Testing
\n
When your items arrive, they are typically tested using basic methods such as a magnet test (to confirm the item is non-magnetic), acid testing (to check karat), or electronic testers for faster readings. Clear testing records should be provided so you know exactly what karat and weight were used to form your payout.
\n\n
Payment Options
\n
Once the buyer confirms your items and their purity, payment usually follows quickly. Common options include:
\n
\n
PayPal: Fast, widely used; fees may apply.
\n
Venmo: Popular for personal transfers; limits on large payments.
\n
Zelle: Instant to linked bank accounts; usually no fees.
\n
Cash App: Immediate; daily limits may apply.
\n
ACH bank transfer: Secure, direct to account; may take 1–2 days.
\n
Check by mail: Simple paper trail; longer to arrive.
\n
\n\n
Safety and Documentation
\n
\n
Keep detailed notes of weights and photos before shipping.
\n
Use insured and tracked shipping.
\n
Save any receipts and tracking numbers until payment clears.

Frequently Asked Questions
\n
How do I tell if gold is real?
\n
Check for karat stamps, try a non-magnetic test, and consider at-home acid testers. Items without marks may require professional evaluation.
\n\n
Can silver-plated items be sold as silver?
\n
No. Silver-plated items have only a thin layer of silver over base metal. Look for \"EPNS\" or \"plated\"—these typically are not purchased for silver value.
\n\n
How do I know what my dental gold is worth?
\n
Because the alloys vary, only precise testing can reveal content. Record weight, and expect buyers to analyze purity before making an offer.
\n\n
Should I clean my items before sending?
\n
Light cleaning is optional, but not necessary. Professional refiners evaluate by weight and purity, not appearance.
