Good question how old currency remains so crisp and fresh. I just came into ownership of two 1862 first issue fractional currency notes. There's not even a tiny corner fold, pin hole, smudge or stain on them. They just had to come out of someone's collection where they were kept safe and dry. But 1862, come on! These beat the odds by a long shot and I'm the lucky one. zeke
I once ordered a multi-volume journal a relatively obscure writer wrote during World War II, and printed in 1947. When it arrived, it was clear the books hadn't been read much; the index looked completely new. When I opened it, a yellowed envelope fell out. In it were six never-circulated Series 1934 twenties. They must have been there for fifty years. Old books are always worth checking for the odd stashed note. Or six.
The local library discarded 2 sets of a bound 1826-1827 magazine into their public book sale. I bought both sets. The pages were irregular in shape and many were not separated yet. So I have two sets of very old magazines that have obviously never been read.
