Parent question: Teenage boys (11-12) collect cards and buy/trade from each other. One kid buys a card from another for $2.00….turns out the card is worth $1,000. Other kids find out, start teasing the kid who got fleeced & his mom finds out and is pissed. Demands the kid return the card to her son. Kid claims he didn’t know it was worth that much at time of purchase. What’s the proper resolution?
