Arizona Diamondbacks Home 2007
Atlanta Braves Road 1972
Boston Red Sox Road 1908
Chicago Cubs Road 1908
Cincinnati Reds Road 1999
Los Angeles Angels Home 1975
Los Angeles Dodgers Home 1971

(and so on...I got tired of looking)

Why can't these be sold?

[Spin_Doctor01_PSN]

I don't understand the SDS concept of not being able to sell items. You should be able to sell anything in your inventory. That whole mechanic is complicated for no reason.

Unlockables from the reward path.

Yup. Should be able to quick sell them, at least.
