What is Coin Identifier?
The Coin Identifier is a sophisticated numismatic tool within the Openclaw Skills ecosystem designed for collectors, hobbyists, and developers. It leverages evidence-based visual analysis to identify coins from user-supplied images, focusing on physical attributes like script, portraits, denominations, and mint marks.
Unlike generic image recognition, this skill prioritizes technical accuracy and numismatic rigor. It provides ranked candidates with explicit confidence levels and cites visible versus missing evidence to ensure a transparent identification process. By maintaining a local memory, it allows users to build a durable, private catalog of their finds without relying on external cloud services.
Coin Identifier Use Cases
- Identifying unknown coins from inherited collections or metal detecting finds.
- Narrowing down specific coin issues based on visible mint marks and dates.
- Documenting a coin collection with local, evidence-based identification notes.
- Pre-filtering coins before submitting them for professional grading or valuation.
How Coin Identifier Works
- Photo Validation: The skill performs a 'photo gate' check to ensure images are clear, isolated, and properly oriented.
- Evidence Extraction: It analyzes the coin based on a fixed hierarchy: country, script, portrait, denomination, date, and mint mark.
- Candidate Ranking: It returns 1-3 potential matches with confidence bands (High, Medium, Low) and lists supporting evidence.
- Refinement: If the signal is weak, the agent requests specific views (e.g., edge, mint-mark crop) to resolve ambiguities.
- Local Logging: Upon user approval, the final identification is saved to a local Markdown-based memory system.
Coin Identifier Setup
To install and initialize the Coin Identifier, use the following commands within your Openclaw environment:
# Install the skill
clawhub install coin-identifier
# Run the setup script to initialize local memory
# This creates the ~/coin-identifier/ directory structure
cd ~/coin-identifier/ && cat setup.md
Coin Identifier Data Schema & Taxonomy
The skill organizes data in a structured local directory to ensure privacy and portability:
| Path | Description |
|---|---|
~/coin-identifier/memory.md |
Stores activation settings and user preferences. |
~/coin-identifier/identifications/ |
Subdirectories organized by YYYY-MM containing individual .md files. |
~/coin-identifier/identifications/{id}.md |
Contains coin label, best match, confidence, and evidence logs. |
~/coin-identifier/exports/ |
Reserved for exporting collection data to other formats. |
Coin Identifier Advanced Features
- Evidence-Based Checklist: Utilizes a specific
evidence-guide.mdto ensure no visual cues are missed during the identification lifecycle. - Confidence Scoring: Implements strict confidence bands (85-95% for High certainty) to prevent false positives in numismatic research.
- Multi-Skill Integration: Seamlessly works with the
imageandimage-editOpenclaw Skills to crop and optimize coin photos before processing. - Privacy-First Memory: Supports local identification notes that are only written with explicit user consent, keeping your collection data off the public web.
