Kindly educate me about NFL Equipment shields

Hi, I've been doing some casual reading through these boards. It looks like the NFL Equipment shield that appears on the collar started appearing in the 2002-2003 season. Also, there are nfl logos that have 5 stars or 19 (?) stars, is this true? what years do each shield align with? Any QUICK help would be appreciated as I'm about to make an offer on a jersey. Thanks so much!!

The NFL changed its logo in 2008 to the 8 starred version. Prior to that it had lots of stars on it, I am too tired to count them now. When Reebok took over the equipment shield was incorporated in their design, that was in 2002. So anything before 08 has multi starred shields and after it is 8 stars.

Thank you very much, that seems simple enough. Thanks, Billsfan.

You're welcome my friend.

I've been lucky enough to track down and acquire a nice haul over the past few weeks. If worse comes to worse, I'll just replace NFL shield logos, as I know the jerseys and customizations themselves are legit. May have just been made a year or two after these players left the Ravens.
