Not a parallel or anything, just a really bad set concept from Topps.
Both are base cards. Why some athletes only got one card while most got two is a mystery known only to Topps.
Edit to add: all of the cards have the standard Silver, Bronze, Gold and US Flag parallels, but I don't know if they all have autograph parallels. The Gold and Flag parallels are SN on the back.
VERY slow trading due to health problems. Not transferrable so safe to trade with, just moving is painful and can't always access the cards.
