I am one of those weird team collectors who get excited to add an obscure player's autograph to my collection. I have a list of former Cardinals who have certified autographs which I do not have. Most cost less than $10, but some do not appear very often. My latest EBAY purchase is a great example.
This 2004 UD Prosigs cost about $7 delivered. I have been searching for this card for a long time. I have seen it at some card shows near St. Louis but I did not like the double-digit price tag. Calero completes my team set. The autographs that year were part of the base set. The throwback uniform is a great look.
To my knowledge, this is Calero's only certified auto in a Cardinals uniform. He does have a couple of autos in an A's uniform. Calero played 2 seasons in St. Louis before being traded to Oakland in the Mark Mulder deal. He was a pretty good reliever for 3 seasons before getting hurt. He finished up his career with 1 year as a Marlin.
