I haven't read this whole thread, so I don't know the distribution of opinions, but here's mine FWIW: Reg. Sec. 1.61-14(a) says "Treasure trove, to the extent of its value in United States currency, constitutes gross income for the taxable year in which it is reduced to undisputed possession." The term "trove" comes from the French "trouver," to find, so it literally means "treasure found." Black's Law Dictionary defines "treasure trove" as "valuables (usu. gold or silver) found hidden in the ground or other private place, the owner of which is unknown; at common law, the finder of a treasure trove was entitled to title against all except the true owner." IRS Pub 17 (and Pub. 525) state:
"Found property.
If you find and keep property that does not belong to you that has been lost or abandoned (treasure-trove), it is taxable to you at its fair market value in the first year it is in your undisputed possession." So, is the ball treasure trove? I'd argue that it is not. It was never lost or abandoned, it was not hidden, and there never was any question as to who owned it. No doubt Major League Baseball, or one of the teams, bought and paid for the ball and owned it before it was hit into the stands. The owner of the ball gave it to the young man who caught it with pure donative intent. He didn't perform any service to earn it. He didn't find it; it was never lost. It's a gift, not taxable. I heard someone on an NPR program a while back say that they had asked four different tax experts whether the ball was taxable income, two said yes, and two said no. We have a similar result here: some say yes, some say no. I'd argue no, but I'm not sure I'd win the argument in court. Clearly if the young man had bought the ball, brought it to the park, loaned it to the pitcher, and Barry Bonds hit it out of the park, the ball would have appreciated in value, but he would have no taxable income until he sold or exchanged it. However, he probably has more use for half a million dollars than he does for a collectible baseball. Which is really why he is auctioning it off. Katie in San Diego
