Berry there are not "only 100" Sundowners. It was a series of six. Meaning there are 600 out there. A lot of members only collect "one from each casino" plus there are not very many members willing to spend even $1200 for the set. One set of Sundowners was offered on Jackpot auction at a starting bid of $1200 and did not receive a bid. So to your question of why, I guess it is "What the market will bare."
