TNH Grading
In numismatics, value lives on two questions: is it genuine, and what condition is it in? TNH Grading answers both with authority — expert authentication and a certified grade that travels with your item.
How it works
1. Submit online
Describe your coin or note and declare its value. You'll get a submission number and shipping instructions.
2. Ship insured
Send the item to our grading room using the packing standards we provide. It's insured from our door onwards.
3. Expert assessment
Our numismatists authenticate the item and grade its condition against consistent, published standards.
4. Certified & returned
Your item comes back encapsulated with a TNH certificate. The certificate is verifiable by anyone, forever.
Authentication first
Counterfeits are this market's biggest risk. Every submission is authenticated before it is graded — weight, dimensions, strike, paper, and printing checked against reference standards.
A grade that travels
Each certificate has a unique number and a public verification page. Wherever your item goes — TNH listing, auction lot, another dealer — the certification follows it.
Visible in the market
TNH-graded items carry the gold badge across the marketplace and auctions — higher trust, faster sales, and typically stronger prices.
