Lately? None, its better than the past with serial numbered cards, patches and autos, there are some hidden gems from back in the 80's and 90s but very rare you'd have any of them
BTW, Topps is out of business for the next 10 yrs, Panini bought the rights for the whole NFL market, including the players in their college uni's which those boxes I really like, Contenders came out about a month ago, 5 or 6 autographs per box, I got:
Laquan Treadwell $60
Devin Johnson $12
Jarran Reed $30
Aaron Burbridge $6
Vernon Adams Jr $30
