## Pricing

from $0.80 / 1,000 record scrapeds

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## CoinArchives Numismatic Auction Price Archive Scraper

Realized and passed auction lot records from the CoinArchives and BanknoteArchives price
archives — ancient coins, world coins, and banknotes sold or offered by roughly 200 specialist
auction houses (CNG, Roma Numismatics, Fritz Rudolf Künker, Heritage World Coin Auctions, Leu
Numismatik, Stack's Bowers, and many others). Each record carries the auction house and sale,
the lot description, denomination, parsed catalogue reference numbers (RIC, Crawford, Sear,
SNG, and more), a realized price normalized to USD, the pre-sale estimate, and whether the lot
sold.

### What it does

Searches the CoinArchives (ancient and world coin) and BanknoteArchives price archives using a
broad built-in term list — major denominations, rulers, mints, and currencies — and returns one
record per lot with a completed auction outcome. Only lots that actually sold or went to
auction and passed are returned; lots listed for a sale that hasn't happened yet are skipped and
will appear once that sale concludes and you run the actor again.

### Input

| Field             | Type             | Description |
|-------------------|------------------|-------------------------------------------------------------------------------------------------------------------------|
| `archiveSections` | array (enum)     | Which sections to search: `ancient`, `world`, `banknotes`. Default: all three. |
| `searchTerms`     | array of strings | Extra search terms to run in addition to the built-in list, in every selected section. Use this to target a specific ruler, coin type, or catalogue number. Optional. |
| `maxItems`        | integer          | Maximum number of lot records to return. Default: 15. |

### Output

Each record includes:

- `lot_id`, `auction_id`, `lot_number`, `lot_url` — identifiers and the canonical lot page
- `auction_house`, `auction_title`, `auction_date`
- `lot_description` — full catalogued description
- `denomination`, `ruler_or_issuer`, `mint`, `catalogue_references`, `grade` — parsed from the
  description; null where the source text doesn't match a recognized term
- `estimate`, `estimate_currency` — pre-sale estimate or starting price, where published
- `price_realized`, `price_currency`, `price_usd` — the hammer price, in its original currency
  and normalized to USD via a live exchange rate fetched at run time
- `is_unsold` — true if the lot went to auction and did not sell
- `image_urls` — lot photo
- `archive_section` — `ancient`, `world`, or `banknotes`
- `scraped_at`

  "lot_id": "2817458",
  "auction_id": "7347",
  "lot_number": "3501",
  "lot_url": "https://www.coinarchives.com/a/lotviewer.php?LotID=2817458&AucID=7347&Lot=3501&Val=1f4705af079f704776b4277e66c28372",

  "archive_section": "ancient",
  "scraped_at": "2026-09-21T12:00:25.920Z"
}
```

### Notes

- `denomination`, `ruler_or_issuer`, `mint`, `catalogue_references`, and `grade` are parsed from
  the free-text lot description, which auction houses write in several languages (English,
  French, German, Italian, Spanish). They populate reliably on well-formed listings and are
  `null` on unusual phrasing the parser doesn't recognize — treat a `null` as "not confidently
  determined," not "absent."
- `price_usd` uses a live exchange rate fetched once per run. It is `null` when the realized
  currency isn't one of the common convertible currencies, or when the rate fetch fails.
- Coverage reflects each auction house's most recently catalogued lots — this is a rolling
  archive, not a fixed historical snapshot. Run the actor again periodically to pick up newly
  concluded sales.

### Resuming a large crawl

Every run emits a `resumeCursor` in its Output. If a large crawl stops before it finishes —
because it hit `maxItems`, your spend cap (`maxTotalChargeUsd`), or was aborted — start a new
run with **the same input** plus that `resumeCursor` to continue from where it left off. The
crawl resumes from the queued work the previous run didn't reach.

- You are **not re-charged** for records the earlier run already delivered.
- Resume within your account's run-retention window — on the free tier, roughly your 10 most
  recent runs. Once the source run is pruned, its `resumeCursor` is no longer valid.
- `resumeCursor` is opaque — supply it unmodified.

# Actor input Schema

## `sp_intended_usage` (type: `string`):

What will this data feed? E.g. lead lists, KYB checks, price tracking.

## `sp_improvement_suggestions` (type: `string`):

Provide any feedback or suggestions for improvements.

## `sp_contact` (type: `string`):

We'll personally help with your use case. No spam.

## `resumeCursor` (type: `string`):

Leave empty for a fresh crawl. To CONTINUE a previous run where it stopped — without paying again for records you already received — paste the `resumeCursor` value from that run's Output (the run's OUTPUT key). Resume promptly: the previous run's data expires with your account's retention window (free tier: your ~10 most recent runs).

## `archiveSections` (type: `array`):

Which free-tier archive sections to search: ancient coins, world coins, or banknotes. Defaults to all three.

## `searchTerms` (type: `array`):

Extra full-text search terms to run in addition to the built-in numismatic term list (rulers, denominations, mints, catalogue prefixes). Use this to target specific coins, issuers, or catalogue numbers -- each term is queried against every selected archive section.

## `maxItems` (type: `integer`):

Maximum number of lot records to return across all search terms and sections.

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
