Independent grading. Clear documentation. Verifiable confidence.
IGA is a specialized authority for authenticating, grading, and documenting coins, medals, tokens, and rare collectibles through a professional methodology that combines careful examination, high-quality imaging, secure preservation, and verifiable digital certification. We do not only assign a grade — we give each piece a documented record that helps preserve its identity, present it with confidence, and support clearer transactions between hobbyists, collectors, and dealers.
A clear, professional standard for every collectible.
Our mission is to provide a clear professional standard for authenticating, grading, and documenting collectibles, helping hobbyists, dealers, and collectors handle items with greater confidence and supporting a more organized and transparent market. We aim for every certificate issued by IGA to become a trusted record for the piece, not just a number or a card — and to become a trusted platform for grading and documenting collectibles in the local and regional market, contributing to a market where information is clearer, pieces are more verifiable, and collections are more organized and valuable.
Building a clearer standard for the collectibles market.
International Grading Agency was founded by a select group of professionals specialized in grading and documentation, with the aim of providing a clearer and more professional experience for the local and regional collectibles market.
We are building a structured standard for handling collectible items, starting from receiving and examining each piece, through grading its condition and documenting its details, and ending with secure encapsulation and a digital certificate that can be accessed at any time.
Our goal is for every piece to be documented in a clear, verifiable way, making it easier to present, sell, buy, or add to a private collection.
Designed for hobbyists, dealers, and serious collectors.
Core principles for every grading process.
Clarity
Each piece is handled through defined steps, so the result is based on a clear methodology rather than a random opinion.
Documentation
A grade has limited value without a documented record. Every certificate is linked to the piece’s registered data and images.
Independence
Grading should be a technical opinion that is as independent as possible, away from exaggeration or unrealistic attempts to increase value.
Verifiability
Every certificate can be accessed and verified digitally, helping reduce confusion during selling, buying, or presentation.
A clear path for every piece.
We believe that proper grading is not based on a quick impression. It depends on structured examination, detail comparison, accurate condition assessment, and documentation of the notes that may affect the final grade.
