Machine damaged.

When we first start collecting coins we find certain ones that look different and we set them aside. After a few weeks, months or even years we later realize they are common. So while out new finds that first discover seem important then, after we have been doing it for a while, then we realize later how common they are later so. So if you find them interesting, same them into a tube. I made the mistake of putting them in 2X2s to only realize this fact later on. Now I have a three ring binder of stuff that I saved and now realize I wasted 4 cents per coin to preserve coins that are only worth one cent. I still save interesting coins into tubes. In case someone has a question on them. I have about 15 tubes labeled that keeps them sorted for quick study. I just save the real extreme ones. The rest I through back or save for wheat cents or for copper. It is like as a kid we find something interesting to collect, like a piece of colored glass. But as were grow older we realize that it is interesting, but later on discover that is all it was at the time.
