MLB hologram HZ 845044
One of just 215 balls signed by the "core four" who led the Mets to the World Series this year. Even if they decide to sign more later, this ball was signed in September, before the playoffs started. They are the first ones to be signed by all four, and I feel their value will be highest over any that might be signed in the future.
These have sold out on Ebay at any price below $600. One just went off at auction for over $900. I have two, an would sell each one for $550...but will not take a penny less.
