52Tunbi is a beginner-friendly guide to collecting U.S. coins. We explain how to start a collection, look after your coins, understand grading and errors, spot fakes, and buy and sell without overpaying. If you’ve inherited a jar of old coins and want to know what you have, you’re in the right place too.
How we work
We check facts against official sources, such as the U.S. Mint for coin programs and specifications, the Federal Trade Commission for consumer advice and the IRS for tax rules, along with established grading standards and numismatic references. AI tools help us research and draft our guides, and an automated check compares them with their sources before publishing.
What we cover
- Getting Started: building a collection, handling and storing coins, and why you shouldn’t clean them.
- U.S. Coins: commemorative quarters, silver coins and error coins.
- Buying and Selling: grading, counterfeits, buying safely and selling a collection.
- World Coins: Canada, Europe, ancient coins and how to start.
- Gold and Silver: how bullion coins differ from collectibles.
- Paper Money: banknotes, star notes and how they are graded.
- Coin History: designers, mints and the stories behind the designs.
- Albums and Supplies: holders, folders, magnifiers and what is safe to use.
Independent
We don’t sell coins or offer appraisals, and no dealer, auction house or grading company pays to appear in our guides. We don’t currently use affiliate links. Coins are a hobby first; we never present them as a guaranteed investment.
