Vintage 1960s coin collection in display case

I was tidying up my desk and realized I left my vintage 1960s coin collection in a clear display case. The case is about 6x4 inches, with a white frame and a few scratches on the glass; inside are coins from the 1950s and 1960s, mostly silver-toned with a bit of patina. There's a rare 1964 Kennedy half and a small brass hinge engraved with a pine-tree symbol on the lid; the inside lid also has a label reading 'Portland Numismatic Club 1972'. I last saw it yesterday around 3pm outside Powell's Books on Burnside in Portland. This collection means a lot to me—my grandfather started it, and I really hope to have it back.
