The reddit poster did show a Game 7 full ticket that sold at a Goldin auction
seen here that sold for $18k...so there is an example of one real full game ticket from Cin game
It came from the estate of a Cin Reds employee who also had an employee pass and a season pass...pretty cool...I missed it when these came into the hobby
