Mason is trying to get his hands on some ancient coins for his new coin collection. I feel like this will be hard work ahead for him, but it's a good project to learn about trading and the value of things.
There are so many eras of ancient coins: Greek, Roman Imperial, Roman Provincial, Byzantine. Some coins are $50 and some are worth thousands of dollars. Since he is buying them with his own money, Mason is working diligently to make sure the ones he wants aren't forgeries. He's speaking with his grandfather about it on a semi-daily basis!
