Your CoinBids data

Private by default: a new visitor starts with an empty collection. Your Collection, Pending, Wishlist and Sales data are saved only in this browser unless you import or export an XLSX file. No personal collection is bundled with the public website.

Price Research

Search across all possible forms/variants, not just exact-string match.

The app analyzes the text and figures out the identity automatically. Just tell it two things before searching:

Metal value (melt value)

Indicative value of the precious metal content, based on the live spot price. Applies only to silver/gold — common alloys (copper-nickel, bronze, steel, etc.) have no meaningful metal value beyond face value.
Automatic live melt value
Metal characteristics: filled automatically from the best validated specification source (CoinBids database, MA-Shops fallback, or Numista fallback). Precious-metal value is calculated automatically as soon as verified weight and fineness are available.

Price findings

The app keeps the offers you find/enter and sorts them by total cost. It can fill in automatically via the backend endpoint.
No prices yet for this search.

Verified catalogue data

Metal composition, weight, diameter and side images — from the exact verified source shown below. CoinBids never guesses missing physical specifications.

Search queries used

Show search details (what was parsed, grade, shipping mode, source)
The face value (e.g. 25 cent) is a coin characteristic confirmed via uCoin. The current market value/selling price is a separate field and should come from research on real listings.
Prices: live automatic search on MA-Shops. eBay has strong anti-bot protection (JS challenge) that can't be bypassed automatically — use the "eBay" / "eBay sold" link below for a one-click search in your own browser. Comparisons should be made between active listings and, where relevant, with total cost including shipping.

Auction Intelligence

Estimate a sensible auction range or decide whether a current bid still makes sense.

Coin & auction inputs

Estimated automatically from validated market listings with known shipping.
CoinBids calculates the auction decision automatically from the resolved coin identity, validated market evidence, known shipping evidence and verified intrinsic metal value when applicable.

Decision

Enter a coin and run the analysis.

Research Settings

How automatic price search works.

Recommended source stack

Catalog identification: Numista (automatic, shown in Price Research). Prices: MA-Shops (automatic) + eBay (2 one-click links). For a serious valuation, keep active asking prices separate from real sold/auction prices.
Live search MA-Shops: runs through a small local backend (Python) on your computer — it has no CORS/proxy restrictions, so it's far more reliable than searching directly from the browser. Open START_COINBIDS.bat (leave its console window open while you use it) and let it run in the background. Without it, Collection/Wishlist/Sales still work normally — only live price search needs the backend.

Why not eBay automatically? eBay protects its search page with a JavaScript challenge ("Pardon Our Interruption") that requires a real browser to pass — no simple automated request reliably gets past it. eBay stays available as a one-click link ("eBay" / "eBay sold" in Price Research), which opens in your own browser and works normally.
