The pillars of stability within the Coin Industry are knowledge, experience, honesty and financial strength. Serious investors should work with a dealer that buys and sells the coins they handle. Many dealers only want to sell coins and may refer you to an auction company as a way of liquidating your portfolio.
This is true for very rare coins but not for bullion or generic ones, and can be an indication they may be charging too high a premium for their coins. You can deal confidently with Eastern Numismatics. Since 1974 we have always purchased back whatever we sold. We will even buy any coins you may have purchased elsewhere. Our staff includes several highly experienced numismatics who combined have purchased well over a $ billion in rare coins. We are members of most consumer and trade organizations including the Better Business Bureau, the Certified Coin Exchange and the Professional Numismatic Guild.
