One Card Post - Shiny Ortiz

What:  2014 Topps Opening Day Blue Holofoil Parallel #51 - David Ortiz (#'d /2014)
Where:  COMC
How Much?:  $1.30
Why?:  Shiny.  Red Sox card I didn't have.  I guess that's about it.  Wow, apparently it doesn't take much to get some of my hobby money.  I seem to have a harder time finding the Opening Day parallels than I do the lower-numbered and in theory more scarce Topps Chrome parallels.  Go figure.  That's probably why I was willing to maybe overpay a bit for this card at $1.30.
Other:  Serial numbered to "just" 2,014 copies!  Also, what exactly is "holofoil" anyway?
