I've been quite proud of myself. Despite being very OCD, I've managed to use various methods of storage/display. I found a few new DANSCO albums for $10 each so I thought, "what the heck" ---- fill few books and have fun with it. To my disdain, it's amazing how scratched the Kennedys get when moving the plastic sleeve open and closed. Very disappointing as I love the look of the album. I put a 1970S cameo in and looked to my surprise -----> horizontal scratches Hopefully a VG date set of Morgans will fair better...
I know it may be too little too late, but I don't put coins into my dansco unless I have all the coins in that row(so I only have to slide the plastic out once). And keep the back sleeve in, push the coins fully against it, then after you slide the front sleeve shut center the coin in the cardboard. On the bright side PCGS says this friction is market acceptable in low ms grades.
Be sure to push the coins all the way "down" before you move the slides, otherwise you'll get the dreaded "slide marks" you describe.
aye... I'm guessing they won't "push thru" ----- > I must admit I've been biten by the Dansco bug ARGH just looks soooo nice
