My two sons just totaled up their discounted value of all the world coins they've sorted, identified, stapled, and stored. I'm lucky that they want some money back out, that'll let me recoup the costs and they can keep the rest as the fruits of their labor
I think my oldest likes do to things I do, my middle one is a natural collector, my daugher I really don't know yet. It certainly is better than another hour of games or TV though. I haven't tried roll searching on them yet. Have you trained your daughter to spy high grade MS coins to send in to PCGS and flip for a profit? Young eyes might be good for that.
