Looking for use on game used baseball jerseys

[captcrunch227]

I frequently read on here to look at the jersey and see if it has any game use. I know how to tell if a jersey is game used/issued from a fake; but telling an issued from a game used I need help on. Can anyone tell me what to look for or point me to an existing thread maybe? I dont know what to look for on a jersey that might help me out. Only thing I know of is if the washtag appears to be worn a bit but other than that I'm clueless. Thanks y'all!

I'm keen to know as well. Things like "pilling" and fading, lose threads ect... a good pictorial in the Exceptionally Educational Threads would be great!
