One easy way to enter the ancient world is to begin a collection of ancient coins. Many coins from ancient civilizations are available for purchase – Persian, Greek, Roman, Ancient Israelite coins to name a few. And though prices of coins vary greatly, you can certainly get started on a modest budget. However, be warned that trying to get a good handle on the different areas and values of coins can be quite challenging, even overwhelming. I suggests picking one area of interests and looking into coins from that one area. You also might want to invest in some collectors guides.
