Maddiedou, appreciate the feedback! Yes, I was wary of Ebay, especially considering my lack of knowledge on the subject. We are also located in BCS. I do not think he has a specific interest. Not even sure this will be a long term hobby, but he did have a coin book/guide that he asked for. From watching him go through coins, I know he pulls out older coins and looks for misprints. I would think anything older, any combination of denomination. For a starter collection, would also be fine with circulated items.
Unfortunately, I cannot DM (no stars) but can send you an email or text.
