Look at these that my brother found while cleaning the house. These are 2 complete tickets to the first regular season Astrodome game Astros vs Phillies. Apparently our grandparents got to the game early and nobody tore up the tickets at the entrance. My brother also has the envelope that the tickets came in. Pretty cool find.
Anybody know an estimated value?

Get them authenticated and they would sell for several hundred

I have uncut tickets to the last game in the dome

I get the allure of a couple hundred bucks, but I'd frame those and hang them in your office. That's a personal family story that's worth preserving IMO.

But then again I have boxes of this kind of stuff that my kids and grandkids will go through one day and who knows what they'll make of it or do with it.
