A Siam (Thai) silver calling card case or matchstick case (often called a vesta case or match safe) is a small, hinged container designed for daily carry in the 1800s and early 1900s. Today, these pieces sit at the intersection of silver collecting, Asian decorative arts, and historical ephemera—so values can swing widely depending on technique (niello vs. repoussé), rarity, and authenticity.
This guide helps you pin down what you have, what features matter to buyers, and how to estimate value using recent auction results (with photo examples). It’s written for collectors, heirs, and sellers who want something more practical than “check the stamp.”

Calling card case vs. matchstick case (vesta): what’s the difference?
The first step is identifying the form—because collectors search and pay differently for each type.
- Calling card case: Usually flat, rectangular, and sized to hold visiting cards. Interiors are plain; no striker. Often 8–11 cm wide.
- Matchstick case / vesta: Smaller, meant for wooden matches. Look for a serrated striker (often on the base) and a tighter fit to keep matches from spilling.
- Cigarette case: Larger, with deeper interior and sometimes elastic straps. Auction houses often group card/cigarette cases together—so make sure the dimensions match.
What collectors mean by “Siam silver”
“Siam” is the historical name for Thailand. In the market, Siam silver usually refers to Thai-made silverwork from Bangkok and other centers, often featuring dense narrative decoration (temples, dancers, elephants, mythic figures). Many pieces are late 19th to mid-20th century; truly mid-19th century examples exist but are scarcer and harder to authenticate.
Key surface techniques: niello vs. repoussé (and why it matters)
Two techniques drive most of the visual identity—and often the value.
Niello (black inlay)
Niello is a black metallic inlay used to emphasize engraved lines and patterns. On Thai cases, niello typically appears as black-filled backgrounds and linework that makes figures pop. Authentic niello tends to sit in the engraved channels (not as a painted layer) and will show age-consistent wear in high spots.
Repoussé (raised relief)
Repoussé is raised decoration formed by hammering from the back and refining from the front. Thai repoussé often features bold relief scenes with high points on figures and borders. The reverse side may show soft tool evidence, and the relief should feel integrated—not like a thin, glued-on plate.
Hallmarks and dating: common pitfalls
Hallmarks on Thai silver can be subtle and vary by period. Unlike British sterling, you won’t always get a full set of standardized date letters. Instead, you may find small pictorial marks, Thai script, or retailer/import marks. A few practical cautions:
- “Siam” marks often indicate 20th-century export/tourist trade (not automatically mid-1800s).
- “Sterling” can appear on later Thai pieces made for Western markets; it’s helpful but not definitive for age.
- Look for a hallmark panel (a reserved cartouche) rather than scattered single stamps—many genuine Thai cases have a small marked zone.
If you believe the piece is genuinely mid-19th century, strong supporting indicators include period-correct construction, consistent wear, and an absence of modern export cues. When in doubt, a jeweler/appraiser can test silver purity non-destructively (XRF) and examine construction under magnification.
Condition checklist (what buyers pay for)
For small silver cases, condition is less about overall “shininess” and more about functional integrity and sharpness of decoration.
- Hinge and clasp: Should close cleanly and align. Repairs, looseness, or replacement pins reduce value.
- Striker (if a match safe): A present, crisp striker is a plus; missing or ground-down strikers are common.
- Edge dents: Small edge dings are expected; deep creases distort the case and hurt desirability.
- Niello loss: Minor loss is normal; extensive patchy loss or modern repainting is a red flag.
- Engraving crispness: Soft, “melted” detail can indicate heavy polishing.
Value drivers and realistic price ranges
For most Siam/Thai silver cases, the market tends to price based on craftsmanship + decoration + size/weight + provenance rather than silver melt value alone.
Typical retail/auction expectations for Thai niello/repoussé cases (broad guidance):
- Entry level (small, simple decoration, later export pieces): roughly $60–150.
- Solid collector range (crisp scenes, good condition, clear marks): roughly $150–400.
- Exceptional (high artistry, rare form, documented early example, strong provenance): can exceed $400 and climb from there depending on venue.
If yours is genuinely mid-19th century, values can step up because fewer survive and collectors are competing for earlier Southeast Asian silver. But the burden is on the evidence: strong period construction and a believable mark story matter more than an optimistic date claim.
Auction comps: recent sales with photos
Here are comparable sales pulled from recent Thai silver auction archives. Note that auction results reflect hammer price, not full “all-in” cost with fees and shipping.
These comps also show an important market reality: even when sellers describe pieces as “antique Siam,” many recorded sales are late 19th to 20th century. That doesn’t make them uncollectible—just price them as the market does, based on workmanship and condition.
How to sell (and how to describe it correctly)
Clear, accurate naming improves both buyer confidence and search reach. A strong listing typically includes:
- Form and function: “calling card case” or “match safe/vesta case,” plus dimensions.
- Technique: “niello” and/or “repoussé,” with close-ups showing the surface.
- Marks: one sharp photo of every stamp; transcribe any readable Thai script.
- Condition notes: hinge/clasp function, dents, niello loss, striker wear.
- Weight: in grams (buyers compare directly across listings).
Care and storage
- Store in a dry environment; avoid rubber bands or PVC plastics that can tarnish silver.
- Use a soft silver cloth for light cleaning; avoid aggressive dips that can attack niello or soften contrast.
- Don’t over-polish: collectors prefer honest patina over rounded, flattened detail.
