KC Royals Silver Platter

I have this Reed & Barton serving tray/platter that is engraved with the KC Royals logo in the center of it. I'm interested to know WHY the logo is engraved in it, perhaps where and what it was used for? There is a "3" on the sticker on the back, so don't know if it's some numbered offering? And of course would like to have some idea of the value. A timely find given the Royals recent World Series win. Go Royals!
