I recently pulled the trigger on a pair of sweet proof sets I've put off buying for years, a 1955 and 1956 set. While there I saw a 1962 proof envelope marked, "never opened", it was reasonably priced. My sceptical nature immediately rose to the forefront, my question to all of you; how do we know it has never been opened? If opened, then resealed, how do you know the coins are legit? It's not hard to reseal an envelope if you are careful. Finally, if this has truly never been opened, how neat is it that a 58 year proof set is unopened? Just wondering what the rest of you thought about this, is this unusual?
Could this set contain a valuable coin, never exposed? Finally, if you purchased this set would you save it for the 100 year anniversary unopened?2 months ago
