Ralph,
I have well over 100. Mostly the Anheuser-Busch ones you referenced, but also Miller, Stroh's and other non-branded ones some older and some newer.
It's funny now but 20-21 years ago my entire chip collection used to reside inside ONE of those steins.
When I moved out here I packed them all up, with the exception of one or two casino related ones, and stored them at my parents.
One of the ones I brought out here is pictured. It's dated 1999.
