My heaviest and lightest coins: This Ptolemy III weighs 85.5 grams, while the diobol from Mysia is a mere 1.1 grams. I just love the variety in ancient coins!

Whenever beginners ask me what they should start their collection with, I always like to recommend a diobol from Kyzikos. It is an ancient silver coin. It features interesting depictions of animals. It is 2,500 years old. There are plenty available on the market, and they are relatively affordable.

It was common in ancient cultures to read texts aloud, even if one was on it's own. When and how did the habit of reading silently develop?
