The 60-Second Silver Check: How to Spot Plate Before You Pay Sterling Prices

You're at a booth in Blue Hills. There's a beautiful pitcher on the table, tagged at $225, tarnished to a deep charcoal color, and the dealer has just said the words it's solid silver. You have about sixty seconds before you either hand over a credit card or set it down and walk away.

This is the post that makes everything we covered in the first and second posts usable in real time. Run through these five checks in order. If a piece passes all of them, you're probably looking at the real thing. If it fails any one of them, it's plate.

Step 1: Does It Say Sterling?

Flip the piece over. On American silver, the word Sterling is the only thing you need to see. If it's there, you're looking at solid 92.5% silver. On British silver, look for a small walking lion, the lion passant. On modern pieces from anywhere, the number 925 stamped on the base means the same thing.

If you see any of those three, the piece is sterling and you can move on to evaluating condition and price. If you don't see any of them, keep going through the checklist.

Step 2: The Wear Spot

This is the single fastest tell on silver plate, and it works on about 80% of plated pieces without needing to read a single mark.

Turn the piece over and look at the base, the back, the underside of a handle, or any surface that would have been handled or set down repeatedly. Silver plate almost always shows a worn, darker spot in the center of the base where the thin layer of silver has rubbed down to the copper or brass underneath.

The spot is usually oval or irregular, darker or pinker than the rest of the piece, and it stands out once you know what you're looking for. Solid sterling and coin silver don't do this. They tarnish uniformly, and because the metal is silver all the way through, there's no layer to wear off.

If you see a rubbed-through spot, it's plate. Don't even bother with the other steps.

Step 3: Is Anything Green?

Silver tarnishes black. It does not turn green. Green is what copper and brass do when they oxidize.

If you see green discoloration anywhere on the piece, especially inside engraving, down in the crevices of decorative work, or around edges where the silver layer is thinnest, that's copper or brass showing through. The piece is plated.

This check is especially useful on ornate Victorian pieces where the decoration creates a thousand little places for the plating to thin and fail. A sterling piece with deep engraving will have black tarnish in the grooves. A plated piece will have green or rusty-looking discoloration in the same spots.

Step 4: The Plate Brand Marks

Certain brand names are plate. Period. No exceptions unless the piece also explicitly says Sterling somewhere else.

• Community: Oneida's plate line. Every Community piece is plated.
• Rogers, 1847 Rogers Brothers, Rogers AA: almost always plate. Rogers did produce some sterling pieces, but those are explicitly marked Sterling in addition to the Rogers name. If the mark is just Rogers, it's plate.
• A1 or AA: these letters refer to the grade of plating, not silver content.
• Triple or XS Triple: means the piece has triple-thickness plating, a selling point for Victorian buyers. Still plate.
• A star mark on some Rogers pieces: also indicates plate.

These marks are plentiful at Round Top. Plated Victorian pieces are beautiful and often a great value for display and daily use, but they should be priced as plate, not as sterling.

Step 5: For British Pieces, Find the Lion

If the piece looks British, has lots of decorative marks, and the dealer is confident it's old English silver, your entire job is to find the lion passant.

The lion passant is a small walking lion in profile, stamped clearly into the metal. It is the only mark that confirms genuine British sterling. Victorian silver plate manufacturers stamped their pieces with elaborate pseudo-hallmarks that mimic the look of real British hallmarks, shields and letters and decorative cartouches, but they never include the walking lion, because by law that mark can only appear on silver that's been hallmarked by a UK assay office.

If you can't find the lion, it's not British sterling, no matter how official the other marks look.

Bonus: Ignore the Tarnish

This is the one that trips up first-time buyers in the opposite direction, when they walk right past genuine sterling because it looks terrible. A blackened, ugly, badly tarnished piece of silver is still silver. Sometimes some of the best finds at Round Top look their worst on the table.

Sterling tarnishes beautifully dark, almost black, when it's been sitting in a china cabinet for forty years. It polishes right back up. A uniformly tarnished piece with no wear-through spots, no green oxidation, and proper sterling marks is often under-priced by a dealer who doesn't want to bother cleaning it for the show.

Check the marks on the ugly pieces. That's frequently where the deals are.

The Checklist in One Breath

1. Does it say Sterling, 925, or carry the lion passant?
2. Is there a worn-through spot on the base?
3. Is there any green discoloration anywhere?
4. Does it carry a plate brand name (Community, Rogers, A1, Triple)?
5. If British, is there a lion passant, or only pseudo-hallmarks?

Two minutes of practice at your first few booths and this becomes automatic. By the end of a weekend at the show you'll be flipping pieces over and reading marks without thinking about it.
