Very nice examples in this thread! Here's an obol that I received as a thank you gift for another purchase. It and the other coin came from a US contractor who was working in Afghanistan. Both coins were purchased in Kabul a few years ago. This diminutive coin of Eucratides, c. 171-145 BCE, weighs 069 grams. As this type goes, it is a pretty decent example, generally well centered and of good metal quality. MIG 181, Bop 9
