Do you have a coin shop in your town? If you do they tend to have a bit of everything (though most likely a focus on coins from the country you live in) and should have a few moderately priced ancient coins to choose from.
I do, but they do not. I'm the Midwest, small towns, coin shops are just very specific pawn shops. They have a fine selection of silver and gold new coins. Thanks for the suggestion though! I may drive to the nearest urban center to look. I hadn't thought of that.
