Might be a bit later then you'd like, most of these were 1910's:

Fenway - 650,000
Hilltop Park - 200,000
Wirgley Field - 250,000
Ebbetts Field - 750,000
Forbes Field - 1 to 2 milllion
Griffith Stadium - 100,000

That actually helps a lot, because it shows how fast the costs increased, and eventually, I will be into the early 20th Century. It's really amazing to think about the fact that the Pirates dropped a cool million plus in pre-WW1 dollars for Forbes Field!
