Good Morning, Yesterday I added a 1880-S Ten Dollar Liberty and a 1901-S Five Dollar Liberty to my small gold coin collection. I also have a Five and a 2 1/2 Dollar Gold Indian coins, the 2 1/2 dollar coin is in slab the other three are in cardboard flips. My question is....I want to put these in a small plastic bag with a zip lock top in my safe deposit box. I need to put a piece of paper in the box to tell my daughter how much I paid for each coin. Will the paper cause any damage to the gold coins? Thanks for any advice!
