Although collectors and investors often worry about counterfeits, it's actually very hard to convincingly fake a gold coin. Gold is extremely dense and to use another metal and gold-plate it would result in a coin that is under-weight, over-diameter or half-again as thick, something that would be spotted very easily by an expert. You can buy from us 100% worry free.
