Lost rare 1992 Upper Deck Ken Griffey Jr. baseball card in protective sleeve at a flea market near Kennewick-Pasco-Richland.

I lost a rare 1992 Upper Deck baseball card featuring Ken Griffey Jr. while attending a flea market near Kennewick-Pasco-Richland last weekend. It was in a protective sleeve and has significant sentimental value to me, as it was a gift from my grandfather. I'm really hoping someone might have found it in the vicinity.
