Estate sale vintage alcohol. Are any of these valuable enough to be worth finding a buyer or can I start sipping?

All sealed and several with the alcohol tax stamp intact. A little google translating informed me of the origins for the non English ones and what they are. It also tells me that based on the meaning and the fact these bottles have labels that don’t appear to be in use anymore, that at least the first two must date back to Soviet era Europe, Hungary and Croatia respectively. The third and fourth are Austrian and Greek, the 5th pic is a mix of stuff (the small bottle with the dude and plums might be Macedonian?) I think the intact duty stamps line up with this, one of the little Seagram’s is marked with 1971.

So for the sleuths, collectors, and alcohol officianados of reddit, would these have enough value to be worth selling or should I just take this as a golden opportunity to taste some history? These aren’t the only ones either. I got a bunch more older stuff from the same place, but I’m posting this from mobile so I’ll probably make a follow up post with others. Thanks for any help.
