Latest: the finds of 2026 (October update)
The headline at the top of this page is real, but it is not new. The gilt-bronze Buddhist figure bought at a garage sale for about $75 sold at Sotheby's New York for $2.1 million in March 2019, after its owner took it to an Antiques Roadshow event in St Louis. It still does the rounds because it has everything: a small price, a big number and an object nobody looked at twice. This year has produced plenty of its own.
A retired decorator bought sealed sets for his son in the late 1990s and left them in binders in the loft for about 15 years: 42 master sets from 1999 to 2009. Ewbank's expects around £250,000 when they sell on 21 October 2026 (Farnham Herald, September 2026).
A woman sorting her late mother's jewellery box found a 1930s Patek Philippe Calatrava, reference 448, in stainless steel, rare for the maker. Estimated at £5,000 to £10,000, it made £59,000 at Hansons in Cornwall on 25 August 2026 (National Jeweler, September 2026).
A Salvation Army shopper paid $6 for a tray marked M, sterling and 02, which collectors traced to the New York firm Mueck-Carey. At 9.3 ounces, its silver alone was put at about $530 (Newsweek, September 2026).
Bought as costume jewellery, it turned out to be 18ct gold set with a 3.02 carat natural diamond, valued at about £15,000 at a valuation day in Oxfordshire (National Jeweler, July 2026).

Notice what most of them have in common: the owner did not know what the marks, the maker or the condition meant. That is the part you can check at home.
The dealer's checklist: what to look for
These are the things we look for first when someone brings in a box from a loft, a drawer or an inheritance, roughly in the order they turn out to matter.
Gold, and the marks that prove it
Look inside ring shanks, on clasps, bar brooches, chain ends and watch cases for a number: 375 (9ct), 585 (14ct), 750 (18ct), 916 (22ct) or 999.
A British hallmark adds a maker's mark, an assay office mark and, on older pieces, a date letter, which lets you date the piece to the year. Broken chains and single earrings count: gold is bought by weight whatever shape it is in.
More: gold hallmarks explained and hallmarks vs makers' marks. Not sure it is gold at all? Run the ten checks in is my costume jewellery real?
Old jewellery: age, stones and signatures
Old cut diamonds, natural pearls, Georgian and Victorian settings and signed pieces are worth more than their metal.
Look for a maker's name on the back or the clasp: Cartier, Van Cleef & Arpels, Tiffany and Boucheron all signed their work, and many signed pieces carry a serial number too.
Read how to tell if jewellery is worth money and signed jewellery values.
Watches, and the pocket watch in the drawer
A stopped watch can still be valuable. Look at the name on the dial, then inside the caseback for the metal and a case number, and at the movement for the maker's signature.
Gold cases are marked 18K, 0.750, 14K or with British hallmarks; "gold filled", "rolled gold" and "plaqué" mean plated.
Guides: identifying an antique gold pocket watch, is my vintage watch solid gold? and full hunter, half hunter or open face?
Silver
Sterling carries 925, "sterling", or in Britain a lion passant with an assay office mark and a date letter. EPNS, EP and "silver plate" are plated base metal.
Heavy pieces such as trays, tea sets and cutlery canteens are worth their weight in silver at least; small Georgian and Victorian pieces by good makers, like card cases and vinaigrettes, are often worth more as antiques.
How to read them: silver hallmarks, EPNS vs sterling and inherited silver.
Coins and sovereigns
Gold sovereigns are the gold coins we see most often in tins, purses and the backs of drawers. A full sovereign is 22ct gold, weighs 7.98 grams and holds 7.32 grams of pure gold, worth … at today's price before any premium for its date or condition.
Look for the year under St George and, on coins struck outside London, a small mint letter. Pre-1947 British silver coins are 50% silver, and pre-1920 ones 92.5%.
Loading the live gold price…
The gold content at the spot price, not an offer. Rare dates and proof coins sell for more.

Pokémon and trading cards
The Surrey loft collection shows why late-1990s and 2000s cards are worth checking. Early English cards from Wizards of the Coast may carry a small "1st Edition" stamp at the left under the artwork, and sealed booster packs and boxes are prized.
Condition is most of the value: a crease or whitened edge cuts the price sharply, which is why the best cards are graded and sealed in slabs by PSA, CGC or Beckett.

Ceramics and porcelain
Turn every piece over. Factory marks, painted or impressed on the base, are the first clue: Meissen's crossed swords is the best known.
Marks were widely copied, though, and Chinese reign marks were often added to later pieces, so a mark is a starting point, not proof. Chips, cracks and old glued repairs cut the value, so look in raking light along the rim.
Boxes, cases and small objects
Gold and silver snuff boxes, cigarette cases, compacts and vesta cases are often the most valuable things in a drawer.
And keep the empty boxes: a fitted box with a jeweller's name in the lid is collected in its own right, and a watch or jewel with its original box sells for more.

Quick checks at home: ten minutes per box
Sort in daylight
Lay everything out on a pale cloth by a window. Keep pairs, sets and anything with its box together.
Daylight, a 10x loupe or a zoomed phone camera, a strong magnet and scales reading to 0.1 g cover most of the checks. Then work through each piece:
- Look for marks
Use a 10x loupe or a zoomed phone camera on clasps, shanks, bases, casebacks and the backs of brooches.
- Try a magnet
Gold, silver and platinum are not magnetic. A piece that jumps to a strong magnet is not solid precious metal.
- Weigh the gold and silver
Scales reading to 0.1 g tell you the floor value of any marked gold. Try the gold price calculator.
- Photograph everything
Front, back and every mark, in focus. It is what a dealer or auction house will ask for first.
Mistakes that destroy value
Most value is lost in the week after the find, by people trying to help.
- Cleaning coins. Rubbing or dipping a coin strips its original surface, and collectors pay much less for a cleaned coin. Hold coins by the edge and leave them as found.
- Polishing silver and watch cases. Heavy polishing wears down hallmarks and chased decoration and removes patina for good. Read cleaning antique silver before you touch it.
- Soaking jewellery. Water gets behind closed-back stones and spoils the foil; pearls, opal, coral and turquoise are easily damaged.
- Splitting sets. A pair of earrings is worth more than two singles, a full parure more than its parts, and a complete canteen of cutlery more than odd spoons. The same goes for an Albert chain with its fob, a watch with its box and papers, and a run of sealed card sets.
- Opening sealed packs. A sealed Pokémon booster or box is worth more than the cards inside it are likely to be.
- Throwing away boxes, receipts and letters. Provenance, the record of where something came from, can add a great deal; a jeweller's box or an old valuation helps prove what a piece is.
- Selling it all by weight before anyone has looked for signed, antique or collectable pieces. Scrap is the floor, not the price: see selling broken and scrap gold.
- Home acid kits and scratch tests. They mark the piece and tell you little about plated metal.
How to get a free valuation
You do not need to pay to find out what you have. Three routes, and what each is good for:
| Route | Good for | Worth knowing |
|---|---|---|
| A dealer who buys | Gold, silver, jewellery, watches, coins and cards; a quick answer and an offer | Ask for a free opinion from photos first. You are under no obligation to sell. |
| An auction house valuation day | Rare single pieces with a likely collector market | Sale results come after buyer's premium is added; the seller pays commission and waits for the sale. |
| A written valuation | Insurance or probate, where you need a document | Usually charged for. For estates, read the probate guide and inheritance tax on jewellery. |
Sorting a whole estate? Start with inherited jewellery: what to do.

Questions we are asked
Is the story of the $75 garage sale Buddha that sold for $2 million true?
Yes. A gilt-bronze figure of the Buddhist deity Cintamanicakra Avalokiteshvara, bought at a garage sale for about $75 to $100, sold at Sotheby's New York in March 2019 for $2.1 million against an estimate of $60,000 to $80,000. The owner had taken it to an Antiques Roadshow event in St Louis.
What items in my loft could be worth money?
The things dealers look for first are gold jewellery and coins, signed or antique jewellery, watches (including stopped pocket watches), hallmarked silver, sealed or early trading cards, marked porcelain, and gold or silver boxes and cases. Original boxes and paperwork are worth keeping with them.
How do I know if something old is valuable?
Start with the marks: carat numbers such as 375 and 750, British hallmarks, makers' names on jewellery and watches, and factory marks under ceramics. Then weigh any gold or silver, photograph every mark and ask for a free opinion before you clean, split or sell anything.
Should I clean old coins or silver before selling?
No. Cleaning strips the original surface of a coin and collectors pay much less for it. Heavy polishing wears down hallmarks and decoration on silver and watch cases. Leave pieces as found.
Are my old Pokémon cards worth anything?
Some are. Early English cards from 1999 to the early 2000s, cards with the 1st Edition stamp, sealed packs and boxes, and cards in very good condition attract collectors. Condition decides most of the value, which is why the best cards are graded by PSA, CGC or Beckett.
Is a gold sovereign worth more than its gold?
Every sovereign is worth at least its 7.32 grams of pure gold. Common dates sell close to that, while rare dates, scarce mint marks and proof coins sell for more.
Should I sell a set of jewellery or cutlery together?
Usually yes. Pairs of earrings, matching parures, canteens of cutlery, and watches with their boxes and papers are worth more complete than split up.
How do I get a free valuation?
Send clear photos of the front, back and any marks to a dealer who buys, or take a single rare piece to an auction house valuation day. We give free opinions from photos, with no obligation to sell.
