Terms of Service
Last updated: July 26, 2026
Introduction
Welcome to NumisNook (“we,” “our,” or “us”). These Terms of Service (“Terms”) govern your use of our website at creditofficer.com and all associated coin-collecting tools, articles, and services (collectively, the “Service”).
By accessing or using our Service, you agree to be bound by these Terms. If you disagree with any part of these Terms, you may not access the Service.
Acceptance of Terms
By accessing, browsing, or using NumisNook, you acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy, which is incorporated herein by reference.
We reserve the right to update or modify these Terms at any time without prior notice. Your continued use of the Service after any such changes constitutes acceptance of the new Terms.
Informational Use, Not Valuation or Investment Advice
NumisNook covers coin collecting and numismatic history only. It does not publish coin valuations, price guides, buy/sell recommendations, or investment advice of any kind, and nothing on this site should be read as a statement of what a coin is worth or a recommendation to buy, sell, or invest in coins, bullion, or precious metals. Our tools provide general, educational estimates for grading terminology, rarity classification, holder and album sizing, metal-content weight breakdowns, possible die-variety matches, and storage guidance. Results are informational only, may be incomplete or out of date, and are not a substitute for a professional grading service, a qualified authenticator, or your own independent research.
Description of Service
NumisNook provides free, practical tools and educational resources, including:
- Coin grade guide (Sheldon scale reference)
- Mintage & rarity scale lookup
- Coin holder & album size finder
- Coin metal weight calculator
- Die variety & error ID helper
- Coin storage & humidity guide
- Educational content on grading, mints, world currencies, and collecting care, and a browsable Coin Museum
All tools are provided free of charge. We reserve the right to modify, suspend, or discontinue any part of the Service at any time.
User Responsibilities
Appropriate Use
Users of our tools and website agree to:
- Use the tools in good faith for legitimate personal purposes
- Provide accurate figures when using our tools
- Not attempt to disrupt or compromise the website’s functionality
- Not use automated systems to access our tools excessively
- Respect intellectual property rights
- Not use the tools for any illegal or unauthorised purpose
Your Own Judgment
You are responsible for your own collecting, grading, and purchasing decisions. Our tools are designed to assist and inform, not to replace a professional grading service, an authentication expert, or your own judgment.
Tool Accuracy and Disclaimers
Calculation Accuracy
Our tools are provided for informational and educational purposes only. While we strive for accuracy, we cannot guarantee that every result will be error-free or suitable for your specific situation. Results are estimates based on standard numismatic conventions and the figures you enter; a genuine determination of a coin’s grade, variety, or condition requires physical examination by a qualified person.
No Guarantee of Results
NumisNook makes no warranties, expressed or implied, and disclaims all other warranties including implied warranties of merchantability, fitness for a particular purpose, or non-infringement.
Not a Grading or Authentication Service
Nothing on NumisNook constitutes professional coin grading, authentication, or appraisal. Grade descriptions, rarity tiers, and variety matches are general references only and do not substitute for submission to a recognized third-party grading or authentication service.

Limitation of Liability
In no event shall NumisNook or its suppliers be liable for any damages (including, without limitation, damages for loss of data or any decision made in reliance on information from this site) arising out of the use or inability to use the materials or tools on NumisNook, even if NumisNook or an authorised representative has been notified of the possibility of such damage.
