A Weirdly Hard to Find Card

Here is my most recent pickup, a 2001 Topps Chrome Retrofractor that I picked up off of COMC.  This card was hard to find for reasons I am not really clear on.  This is the first time I have seen one pop up on any site.  I have seen the Traded Retrofractor a number of times, but this one took awhile to pop up.  Oh well.  I have it now.
