Help identifying
 

So I can't find out what these are
They are 4x5 so it rules out jay bulishing
They are a glossy white photo paper
I have 29 of them and they are all NY Yankees
Thanks for any help

That's the 1974 Syracuse Chiefs team issue which combined Yankee minor league players, then current major league players and Yankee All Time Greats. There should be 30 cards in total.

Wow thanks I'm having a hard time locating a value on these
Anybody have an ideas what they are worth
