When finding a rare coins dealer offering Roman gold coins for sale, check the dealer's credentials.
Are they regulated by any official groups or societies? Who does their authentication? Are they a member of the American Numismatics Association, or the Industry Council for Tangible Assets? Are they in good standing with the Better Business Bureau? These are among the more important things to consider when finding a company who deals with the sale of gold coins, Roman or otherwise, for your collecting hobby or investment needs.
A coin collector, particularly a collector of coins minted of silver or gold, is looking for a sound investment.
Gold and silver can be appraised fairly simply, as far as the purity of the metal is concerned.
But when we find a source which deals with the sale of gold coins, be they for hobbyists or for serious investors, there is a need for authenticity documentation, especially if the item can be as old as Roman gold currency.
It's just too serious an investment for anything less.
See to it that you are dealing with a well regulated dealer.
Do some research into the company's credentials and check up on them to see if they are a legitimate distributor of the genuine item.
Ask around and inquire of others in your community of collectors and investors as to the quality of the company that you find.
When looking for suppliers of coins for sale, especially Roman gold, check into the authenticity of the supplier's wares.
Without authenticity, you haven't got much.
