Yeah you got a point there in regards to reducing the value. But do you have any intentions of selling the item. More than likely it'll stay in your collection. Picked up a sealed mono original of Folk n Roll from the local record store a couple of months ago,opened it and played it, no big deal.Collecting can go overboard, next step bubble wrapping everything that's rare. The return ain't worth it, play it and listen while you still can.
Until next time
