There's no doubt in my mind that kids buy and sell stuff all the time, and usually it's not a problem, but when junior takes $500 out of dad's wallet and spends it on baseball card packs to try (and fail)to get a rare $100 chase card, you can bet the law will come into play.

I bought and sold thousands of dollars worth of coins before I was 18, but business was mostly with adults and I was using my own money to do it. Heck, I was borrowing money without a co-signer when I was 16 and the legal age was 21. It was many years later that I found out that the documentation was put in the desk of one of the bank board, who was a good customer, and was in effect covering the loan.

As far as turning down kids, a nine-yo boy went into a friend's store with $300 cash and wanted to buy a krand. The clerk asked the owner, who told the kid to come back with a parent. Mom comes over and says "it's OK, I think it's silly, but that's what he wants to spend his money on. And you might as well pull out two, because she (pointing to six-yo sister) wants one too."

If you don't think it applies, sell a coin with a nude on it to the kid whose folks are prudes, and watch what happens.
