Help with liquor ID

Hello fellow drinkers,

​

My coworker’s father just recently passed away with a little bit of a collection. The story I was told is that the father worked at GE and had been gifted the bottles over the years in the 70s. The man wasn’t much of a drinker and left many of his bottles in their plastic/seal.

​

My coworker brought it to me (I guess I’m the expert bc I can drink😅) and asked if I could figure when they’re from and if they’re worth anything. The only one I can ID is the gin because it was made for a local, now defunct, famous liquor store. Also, I believe the Seagrams is from the late 60s or early 70s. Any help is greatly appreciated!
