Vintage 1977 Luke Skywalker figure, mint on card

I lost my vintage 1977 Luke Skywalker action figure, mint on the original card, yesterday around 3pm in Southwest Michigan, after browsing Hall's Hobby Shop on State Street in downtown St. Joseph, near Silver Beach. The figure is in its blue Kenner packaging with the basic 'Star Wars' logo; there’s a small crease along the top-right corner of the card and a faint coffee stain on the back. It means a lot to me—it was my dad's favorite piece and now part of my own growing collection, so I really need it back. If anyone found it near the shop, the marina area, or around Silver Beach, please reach out.
