Up for sale is a cermonial first pitch home plate from Opening Day 2005: Arizona Diamondbacks vs. Chicago Cubs on April 4th, 2005. Ryne Sandberg & Mark Grace threw out the first pitch to this homeplate, and it has the MLB hologram on it (MT 00396493). The plate is 21x21 and pretty heavy. My asking price is $100 which includes priority mail shipping with delivery confirmation.
