About the tools
A few useful things to know, whichever tool you choose.
How do I choose the right tool?
Each directory entry explains its purpose and the information it works with. Open the tool to see its supported inputs and instructions. If your question falls outside that scope, explore the collector guides for more context.
How should I use a result?
Use it as a starting point for the question that tool addresses. Calculations depend on the information entered and any stated assumptions; checks depend on the rules they cover. Read the explanation and scope on the individual tool page.
Can a tool replace an expert assessment?
Tools can help you organize information and explore specific details. Authentication, professional grading and a market appraisal require a broader assessment of the actual item and relevant evidence.
Where will I find new tools?
New tools will appear in the directory above as they become available. Each will have its own page with instructions and an explanation of its results.
