Resource for "significant" ticket stubs?
 

I was wondering if any ticket collectors know of an online resource for identifying sporting events in which something significant transpired (ie "first game," "first home run," "first start," etc.). I have a substantial amount of season ticket stock tickets from the past 12 years (MLB, NBA, NFL and a TON of college football), but it is hard to know which ones might have collector interest. I stumbled upon some Trout MLB debut tickets by doing a random search on Ebay, so now I am wondering what other treasures might be hiding in the banker's boxes full of tickets I have in the garage.

Any help would be appreciated. Thanks.
