Instructions
Decide what type of currency you want to collect, such as coins, banknotes, currency from specific countries, continents or time periods. Think about affordability as well when deciding where to get started with currency collecting. Currency from certain historical time periods can be expensive, so you may want to start small while building your knowledge.
Learn everything you can about numismatics, or the study of currency. Invest in books that cover your chosen currencies and study them carefully. Become an expert on old currency to help you find excellent additions to your collection, as well as to protect yourself from fraud. The American Numismatics Association, or ANA, suggests purchasing or borrowing books that detail mistakes to look for on old currency, as these pieces can be extremely valuable.
Find currency for your collection once you have developed enough knowledge of your chosen specialty. Check out estate auctions, online collection auctions, coin shops and numismatic organizations to find items you want to add to your collection. Take pricing guides with you to help make wise purchases for your collection.
Learn the proper handling procedures to protect your currency acquisitions. Keep bills and coins in archival sleeves and capsules to reduce damage from chemicals and the oils in your skin. The ANA suggests storing your currency in an airtight container, kept in a cool and dry environment to prevent damage from poor air quality and dampness.
