it matters
According to http://www.baseball1.com/faqs/ticket_prices.html, the average Major League baseball ticket price in 1950 was $1.60.
55 cent back in the early 1830
25 cents
I believe that beleacher seats were around a quarter. This is only a guess, but i do know that the seats for a Chicago White Sox bleacher seat raised to 50 cents in the 1920 season.
