[QUOTE="jeankay, post: 346548, member: 12159"][b]Mint wrappers[/b] After receiving my first few 60's mint sets in those yellow envelopes with the two pieces of cardboard meant to protect them I realized that upon opening the supposedly unopened sealed envelope (they were not suppose to be sealed shut in the first place) the contents smelled extremely musty. Like an old book in a library. A musty environment is not a place where I would want to store anything, much less lovely coins. After all, did they have acid free cellophane, cardboard or envelopes in use at the mint in 1960? I doubt it. Apparently it was in the 1950's when acid-free paper was made possible by technology. Unfortunately it took decades until ANSI NISO Standard Z39.48-1984 when the standards were adopted. Just a point of view about those protective envelopes... jeankay[/QUOTE]
