I have about 50 of these from each of the past four years. The values don't drop that much except for "hot" rookies that eventually cool down. I pulled a Trout, a Conforto and a Seager out of one trip. Well worth the $9 I spent that day. The Trout is PC but thinking of offering the others up for trade while the values are high.
