Did you take those out of flips or other types of storage to photograph them? They should definitely be in some protection to admire without handling them.
All of my key gates, mint states, and expensive ones (Hawaii half and 20 cent coin) are all in a flip, rest of the junk silvers are in a ziplock bag!
Sweet collection. I might offer a small suggestion. Plastic storage tubes are incredibly inexpensive. They would store your silver coins more effectively and would avoid any abrasion the coins may experience in a ziplock type bag. Keep at it! That silverbug is a hard one to shake!
