Winning bids for Mantle, Mays, Robinson, Palmer and Brock Autographs

In the previous post I talked about The Topps Vault releasing contracts from the 1987 Topps K-Mart 25th Anniversary Baseball Trading card set and putting them up on EBay.  Well those auctions are now closed and the wining bids are in.  Here are the final prices paid, in US dollars, for the contracts behind the cards you see above.

Lou Brock - $129.50
Jim Palmer - $208.59
Brooks Robinson - $169.59
Willie Mays - $409.00
Mickey Mantle - $910.00

Did anyone following us have the winning bid?  What do you think of these prices?
