Buying rare coins can be risky because of the absence of consumer protection standards. Coin investments carry no guarantee of a profit do not pay interest or dividends generally must be held onto for several years and do not appreciate rapidly. Liquidity may also be an issue to consider. If necessary to liquidate your investment how easy would it be to find a buyer?~~Before making a buying decision have an independent source verify grading and pricing. Remember grading is the opinion of the appraiser and involves some degree of subjectivity. Age and rarity may be decisive factors in determining values but the ultimate value is determined by the price a collector is willing to pay. Do comparative shopping and research. If purchasing from a dealer or broker find out if your contract has buy-back provisions in the event you need to liquidate. Ask about refund and exchange policies. Verify the authenticity of your delivered coins and get any representations or promises concerning projected resale values in writing.
