You are charged both the fixed price for specific events and for Apify platform usage. Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. 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. Actors are written with capital "A". ## 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. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## NGC Coin Catalog Scraper Browse the **NGC numismatic coin catalog** — list all coin series by name or search for specific series, and enumerate individual coin types (year/mint/denomination entries) within any series. Data sourced from the public NGC coin research API (`production.api.aws.ccg-ops.com`). ### Data Source Data is sourced from the **NGC (Numismatic Guaranty Company) public coin research API**, which powers the NGC Coin Explorer website. No authentication, proxy, or cookies required. ### What You Can Do - **List Coin Series** — browse all 15,000+ numismatic coin series in the NGC catalog - **Search Coin Series** — find series by name (e.g. "morgan", "lincoln", "eagle") - **List Coin Types** — enumerate all individual date/mint entries within a specific series ### Input Parameters | Field | Type | Default | Description | |-------|------|---------|-------------| | `mode` | select | `searchSeries` | Operation mode | | `query` | string | `morgan` | Series name keyword (modes: listSeries, searchSeries) | | `seriesId` | integer | `72` | NGC research group ID for listCoinTypes mode | | `maxItems` | integer | `50` | Max records to return (1–500) | #### Modes | Mode | Description | |------|-------------| | `listSeries` | List all coin series (paginated) | | `searchSeries` | Filter series by name keyword | | `listCoinTypes` | List all coin type entries for a specific series | #### Well-Known Series IDs | seriesId | Series | |----------|--------| | 72 | Morgan Dollars (1878-1921) | | 78 | Peace Dollars (1921-1935) | | 45 | Buffalo Nickels (1913-1938) | | 19 | Silver Eagles (1986-Date) | | 18 | Silver Commemoratives (1892-1954) | | 13 | Early Dollars (1794-1804) | | 14 | Gold Dollars (1849-1889) | ### Output Fields #### Coin Series Records (modes: listSeries, searchSeries) | Field | Description | |-------|-------------| | `seriesId` | NGC research group ID | | `seriesName` | Series display name | | `seoName` | URL-safe series name | | `importCode` | NGC import code | | `categoryId` | Category ID | | `categorySeoPath` | Category URL path | | `subcategorySeoPath` | Subcategory URL path | | `totalPopulation` | Total NGC-certified coins in this series | | `populationNGCX` | NGC Exchange certified count | | `hasMintStateCoins` | Whether MS-graded coins exist | | `hasProofCoins` | Whether PF-graded coins exist | | `description` | Series description | | `recordType` | Always `"coinSeries"` | #### Coin Type Records (mode: listCoinTypes) | Field | Description | |-------|-------------| | `coinTypeId` | Universal coin type ID | | `populationId` | NGC population record ID | | `year` | Year (may include variety, e.g. "1878 8TF") | | `numericYear` | Numeric year | | `denomination` | Denomination (e.g. "$1") | | `mintMark` | Mint mark (S, O, CC, D, or empty for Philadelphia) | | `designation` | MS (Mint State) or PF (Proof) | | `strike` | Strike type | | `variety` | Variety description | | `displayName` | Full display name | | `seriesName` | Parent series name | | `seriesId` | Parent series ID | | `totalPopulation` | Total NGC-certified count for this type | | `recordType` | Always `"coinType"` | ### FAQs **Does this require an API key?** No. The NGC coin research API is publicly accessible. **How is this different from NGCCoinCensusScraper?** This actor returns coin series info and coin type identification data (year/mint/denomination). NGCCoinCensusScraper returns full grade-by-grade population breakdowns (MS60, MS61...MS70 counts). **How many coin series are in the catalog?** Over 15,000 coin series from all countries and eras. **What's the daily test prefill?** mode=searchSeries, query=morgan — always returns Morgan Dollar related series. # Actor input Schema ## `mode` (type: `string`): What to fetch from the NGC coin catalog. ## `query` (type: `string`): Keyword to search coin series by name (mode=searchSeries). Example: morgan, lincoln, eagle, dollar. ## `seriesId` (type: `integer`): NGC research group ID for the coin series to list coin types from. Example: 72 = Morgan Dollars, 78 = Peace Dollars, 45 = Buffalo Nickels. ## `maxItems` (type: `integer`): Maximum number of records to return. ## Actor input object example ```json { "mode": "listCoinTypes", "query": "morgan", "seriesId": 72, "maxItems": 50 } ```` # Actor output Schema ## `results` (type: `string`): Dataset containing scraped NGC coin series and coin type records. # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "mode": "listCoinTypes", "query": "morgan", "seriesId": 72, "maxItems": 50 }; // Run the Actor and wait for it to finish const run = await client.actor("crawlerbros/pcgs-coinfacts-scraper").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
