1960s Yankees Wool Warm-Up Jacket

[both-teams-played-hard]

I assume this jacket was issued to a scout or coach, because I cannot identify any player with these initials. Mid 1960s MacGregor tagging. It is heavyweight wool, just like a letterman's jacket. There are some very tiny moth-holes in the cuffs and collar, but still very clean. Has anyone seen one of these for sale at auction? What could a jacket like this be worth? I am not a Yankees fan, so I will most likely sell this jacket in the future. It's so nice that I may become a fan!
