We have a tall set of bookshelves that I keep some things like that on in one room. It contains pictures of my Grandad, myself as a boy, the two fo us together, and my grandsons. Amongst those pics are memorabilia of parts of our outdoor past. Grandad's Pflueger Supreme reel, duck call and his huge old railroad padlock and key are there. There are a few unique prizes from shoots I've won, like a scrimshawed powder horn from the Charlestowne Longrifles club one year when they hosted the S.C. State M/L Championship. There are a couple full boxes of magnum paper duck loads by Grandad's duck call......... and other stuff. From time to time an item may be added. My wife has no issue with dusting it all. She does it once a week, along with every other "knick-knack" of hers in the house.
Most of my shell boxes and other junk are in another location, lined up on shelves. You just can't have too many shelves. If I could start over I'd just build an entire separate building adjacent to the house for all the reloading stuff, pictures, prints, collections, gun cleaning stuff, shells, trophies, etc.
