(Temecula, California) -- Rare coins increased 10 percent in value over the past year and have increased 227 percent the past ten years, according to the Luxury Investments Index in the recently-released Knight Frank 2014 Wealth Report. The Professional Numismatists Guild (http://www.PNGdealers.org/">www.http://www.PNGdealers.org) estimates the vibrant U.S. market for high-quality, rare coins was about $5 billion in 2013 with a dozen individual coins selling for $1 million or more at auction last year.
However, numismatic experts caution that before making a rare coin purchase investors should beware of unscrupulous "boiler room" dealers who may promise more than they deliver.
"Rare coins are an enjoyable hobby and part of some people's long-term portfolios, but buyers should remember the important adage: If you don't know rare coins, you better know your rare coin dealer," said Terry Hanlon, President of the Professional Numismatists Guild (PNG).
Founded in 1955, the PNG is a nonprofit organization composed of many of the country's top rare coin and paper money dealers. PNG members must adhere to a strict Code of Ethics in the buying and selling of numismatic merchandise.
"As with stocks, bonds, fine art or real estate, the numismatic market is a highly specialized field," explained Hanlon.
"We encourage buyers to read about coins, learn the basics and work with a professional, expert dealer before making a large investment. PNG members must demonstrate knowledge, responsibility and integrity in their business dealings, and must agree to binding arbitration to settle any unresolved disagreements over numismatic property."
