It is important to exercise caution when purchasing coins. You should know your dealer and make sure they are experienced and reputable. Most dealers offer a "grace period" to allow inspection and return (if you are not satisfied) of numismatic purchases. No one dealer can specialize in all types and denominations of coins so if you are interested in many different types of coins you may have to seek the advise of several suppliers.

Even expert numismatists and specialists have to occasionally seek advise. If you are a novice a good way to begin your quest for knowledge is to simply purchase a "Red Book", subscribe to "Coin World", and "Numismatic News".The aforementioned publications both issue a supplemental "Trends" or "Pricing Guide". A subscription to "CDN" is highly recommended. "CDN", "Coin Dealer Newsletter" sets the " industry" standard and offers continual market pricing to the Dealer and the Collector.

The best way to gain exception in this industry is to attend trade shows and compare coins, grades, and prices at different tables on the bourse. Even if you are a seasoned veteran it is imperative to keep abreast of the ever changing coin market.
