The easy explanation as to why I have such a collection is that when I was 15 I started working at a high paying position in a large coin store. I managed to impress the owners with an uncanny knowledge of ancient numismatics. I'm 18 now, and my collection is much, much larger - perhaps quadrupled in size. My latest acquisition is a gold Stater of Alexander III (The Great) of Macedon. I expanded into Byzantine gold and Spanish Colonial silver, finished my type set and gold type set and acquired a few more U.S. gold coins just as an investment. I'm also hoping to deepen my knowledge of Islamic coinage of the Ummayad and Fatimid Caliphates, and for my next large purchase I hope to acquire a half Mnaieon of Ptolemy III or an Aureus of Nero.
