Do gold bullion bars have to stay in there package to keep there value?

Jason asked:


Now days almost all the 24k gold bullion bars you find for sale come in a package, like a card they are sealed into from the refinery, I am speaking of smaller bars from 1 gram to like 1 ounce bars some others too. I am curious, if I bought 50 gold bullion 1 gram pieces would they lose value if I took them out of there package or be harder to resale in the future or prove there purity?
