authenticated & graded by NGC/PCGS silver or gold coins from Ancient Greece/Rome or from the Medieval Era (477 A.D. - 1600 A.D) for sale please let me know what you have and how much you’re looking for. Im looking to buy denarii, drachmae, aureus/aureii (sp?), solidii, and many other coins of this type if they are silver/gold. I am not looking for copper, bronze, brass, etc., coinage. Thank you!
