They gave out only 10,000 at the games, but the first two years (Yount, Uecker, Jenkins and Sexson, Sheets, Aaron) were also available via mail order. I also remember the Brewers selling some of these at the clubhouse store. For some of the bobbles, you can tell the difference between a game give-away or a purchased one (different sponsor on the base of the bobble). I don't know if there is a premium value on one or the other type.
