The full boxed 64 Banquet sets do not show up very often. The individual cards show up from time to time on ebay. I think PSA or someone grades them. Below is a link to sales of some in REA.
I would guess the players got trophies but they may have been cheap ones, otherwise you would think some of them would have shown up in auctions somewhere
