Two tickets for October baseball between the Toronto Blue Jays and your Seattle Mariners 😉. 

As a kid, walk down the Kingdome ramps after a game, I used to pick up ticket stubs that people dropped and then kept them in a shoebox.

If I used the CPI calculator correctly, $5.50 in 1981 would be about $21.00 in 2025 for 100 level seats.
