In short
Yes, but not much per piece, and almost nobody on a high street will pay for it. A chain stamped 1/20 14K GF carries 5% of its weight as 14k gold, which is 2.9% fine gold: a 20 gram chain holds about 0.59 grams, worth $82.92 at today's spot. A pawn shop or jewelry store tests the surface, finds a layer, and hands it back. Refiners buy gold filled, but by the pound and on assay: a pound of mixed 1/20 14K scrap yields roughly 13 grams of fine gold, about $1,842.57 before the refining charge. So the answer for a drawer of old gold filled is either to sell the good pieces as vintage jewelry, which usually pays more than the gold, or to save it until there is a pound and send it to a refiner with your karat scrap.

What the stamp promises, in grams
Gold filled is a sheet of karat gold bonded to a brass core, and US rules tie the word to a weight fraction: the gold layer has to be at least 1/20 of the total weight and at least 10 karat. The stamp says both numbers. 1/20 14K GF means five percent of the weight is 14k gold; 1/10 12K GF means ten percent of the weight is 12k gold; 1/40 12K RGP, rolled gold plate, is half the gold filled minimum and may not be called gold filled. Multiply the fraction by the karat and you have the fine gold.
| Stamp | Gold layer, share of weight | Karat of layer | Fine gold, share of weight | Fine gold in a 20 g chain | Worth today |
|---|---|---|---|---|---|
| 1/5 14K GF | 20% | 14k | 11.7% | 2.34 g | $331.66 |
| 1/10 12K GF | 10% | 12k | 5.0% | 1.00 g | $141.74 |
| 1/20 14K GF | 5% | 14k | 2.9% | 0.59 g | $82.92 |
| 1/20 12K GF | 5% | 12k | 2.5% | 0.50 g | $70.87 |
| 1/40 12K RGP | 2.5% | 12k | 1.25% | 0.25 g | $35.43 |
| HGE, 2.5 µm plating | a film | any | about 0.1% | 0.02 g | $27.36 |
Who buys it, and what they pay
Two kinds of buyer exist and they behave differently. A storefront buyer, a pawn shop, a jewelry store, a mall kiosk, tests the surface with acid or an electronic tester, reads the stamp, and refuses gold filled outright or offers a token, because they resell to a refiner by karat and cannot grade a layer. A refiner melts and assays, so the layer does not matter, only the recovered gold. Refiners buy gold filled routinely, in lots, and settle on the assay against the day's fix, minus a refining charge that appears on the settlement statement. One refiner's own figures: a pound of mixed 1/20 14K scrap carries roughly 13 grams of fine gold, $1,842.57 at today's price, and a pound of 1/5 14K material about 53 grams, $7,512.03.
The catch is size. A few grams of gold filled chain will not cover insured shipping and the charge; refiners say so themselves and suggest adding gold filled to a mixed lot with karat gold so the whole shipment clears. Read the terms for a minimum lot, a stated refining charge, and settlement on recovery rather than on a counter estimate. The selling guide covers the mail-in process and how to read an offer as a share of melt.

The fraction on the stamp is the fraction when the piece left the factory. Every year of wear removes gold from the surface, and the layer is only tens of microns thick, so a fifty-year-old 1/20 12K watch chain with brass showing at the links can be down to half its original gold. Refiners and scrap forums use 2.5% as a rule of thumb for mixed 1/20 12K lots and warn that worn material comes in under it. Pieces that never rubbed, brooches, pins, eyeglass temples, hold close to the stamp. Chains, bracelets and watch cases hold less.
Solder and findings matter too. Clasps, jump rings and pin backs on gold filled pieces are often base metal, and a mixed lot is priced on what the crucible recovers, not on the stamps in the bag. Sort out anything marked GP, HGE or with no stamp; it dilutes the lot and pays nothing.
When it is worth more whole
The gold in a gold filled piece is often the least valuable thing about it. Victorian and Edwardian watch chains, Art Deco eyeglass frames, mid-century American makers who sold gold filled and gold overlay as their main line, and any piece with intact enamel or stones sells to collectors for several times its gold content, because buyers of vintage jewelry pay for the object. A refiner pays for 0.6 grams of gold; a collector pays for a chain.
- Check the maker's mark before the metal mark: a known name on a gold filled piece changes the market it belongs in.
- Sell intact pieces through vintage jewelry channels, consignment or auction, and scrap only the broken, worn or anonymous ones.
- Never melt a piece that could be repaired and worn; a decade of wear is what gold filled is for, and a working chain is worth more to a wearer than to a crucible.
Telling gold filled from solid and from plated
| Check | Gold filled | Solid gold | Gold plated |
|---|---|---|---|
| Stamp | GF, 1/20 12K, 1/10 14K, RGP, gold overlay | 10K, 14K, 18K, 585, 750 with a maker's mark | GP, GEP, HGE, or nothing |
| Wear points | brass at edges only after years | same color all through, ever | brass at edges within weeks or months |
| Density | about 8.7 to 9 g/cm³, a brass core | 11 to 15.6 by karat | about 8.5, brass |
| Acid on the surface | passes; the surface is karat gold | passes | passes until the layer is scratched through |
| Acid on a filed notch | brass reacts under the layer | passes | brass reacts |
| Magnet | no | no | no, unless the core is steel |
The surface test is the trap. Gold filled is real karat gold on the outside, so a touchstone streak or an electronic tester reads 12k or 14k and a careless buyer pays solid prices; a careful buyer files a notch in a hidden spot or weighs the piece against its volume. The testing page has the density method, and the stamp decoder reads the fractions.

Take a realistic drawer: 60 grams of assorted 1/20 12K chains and bracelets, some worn. At the stamp value that is 1.5 grams of fine gold, $212.60 today; at a worn-lot yield of 2% it is 1.2 grams, $170.08. Insured shipping both ways and a refining charge come off that, and many refiners will decline the lot on its own. Sent along with a few karat gold pieces, it adds its gold to the settlement at almost no extra cost. Sold as jewelry, the two or three best chains in the drawer probably fetch more than the whole lot melted.
The scrap calculator is built for karat gold, but the same formula works here with the fine gold fraction from the table above in place of the karat: weight × fraction × spot, then the buyer's percentage.
Scrap payoutA mixed lot: melt value and what buyers actually payOpen calculatorIs it worth buying?
As jewelry, yes, and this page should not put anyone off it. Gold filled is the durable middle between plating that lasts a season and solid gold that costs ten times more: tens of microns of real karat gold that survive a decade of daily wear, do not turn skin green while the layer lasts, and can be worn in a shower. As an investment or a store of value, no: the gold inside is a few percent of the weight, a fair price for a gold filled piece is two to four times a plated one and a small fraction of solid, and nobody will buy it back for its metal. The filled, plated and vermeil guide puts the three side by side with cost per year of wear.
Questions people ask
Is gold filled worth anything at a pawn shop?
Usually nothing. Pawn shops and jewelry stores buy by karat and resell to refiners by karat; a layered piece cannot be graded that way, so they test the surface, see the GF stamp or brass at a notch, and decline or offer a token. Gold filled sells to refiners by the pound on assay, or as vintage jewelry to people who want the piece.
How much gold is in gold filled jewelry?
Read the fraction and the karat on the stamp. 1/20 14K GF is 5% of the weight in 14k gold, which is 2.9% fine gold; 1/20 12K is 2.5%; 1/10 12K is 5%; 1/40 RGP is 1.25%. A 20 gram 1/20 14K chain holds about 0.59 grams of fine gold, worth $82.92 at today's spot. Worn pieces hold less than the stamp says.
Can you sell gold filled jewelry for scrap?
Yes, to a refiner, and usually only in quantity. Refiners melt and assay, so they pay for the gold recovered regardless of the layer; one quotes about 13 grams of fine gold per pound of mixed 1/20 14K scrap. A few grams will not clear shipping and the refining charge, so save gold filled until there is a pound, or add it to a lot of karat gold scrap.
What does 1/20 12K GF mean?
One twentieth of the piece's weight is 12 karat gold bonded to a brass core: 5% of the weight is 12k alloy, and 12k is half gold, so the piece is 2.5% fine gold by weight. It is the most common gold filled grade. 1/10 means twice the gold; RGP, rolled gold plate, means half the gold filled minimum.
Is gold filled real gold?
The layer is real karat gold, tens of microns thick and legally at least 10 karat and one twentieth of the weight. The piece as a whole is brass with a gold skin, so it is real gold on the surface and base metal by weight. It wears like gold for years and is worth cents to a few dollars as metal.
How can I tell gold filled from gold plated?
The stamp, the density and time. Gold filled is marked GF, 1/20 12K or RGP; plated is GP, GEP, HGE or unmarked. Both weigh like brass, about 8.5 to 9 grams per cubic centimeter against 13 for 14k gold. Plating shows brass at the edges within months; gold filled takes years. An acid test on the surface passes both, so file a notch or weigh.
