That is pretty neat. Certainly something that should be held on to! Not to steal your post, but...
I actually have four (well, three in my possession) tickets from the Army/Notre Dame lacrosse game that was supposed to be played in April. They arrived in the mail the same day that the ACC announced they were suspending all spring events, and they're now a unique collectible for me.
My dad still has a Notre Dame/Purdue football ticket dated September 15, 2001...of course, that game was rescheduled and ended up being played December 1, 2001 instead. Two unrelated events, but both with some eerie similarities when it comes to the sports world, and he now has one of the four Army/ND tickets from 2020 to put next to the ND/Purdue one.
I wonder if anyone else has something similar?
I'll never quit collecting entirely, but I am downsizing. Check out my COMC store and help me thin out what I don't want so I can buy cards that I do want. See something you like? Send me a message on here, and we can knock the price down quite a bit. I'll even take a bit of a loss if it means getting you a card you really want.
