I went back to a park that I found the 1906 Indian head penny, and a bunch of wheaties. I found my first ever Mercury dime!I found this military button and don't know about it or how to clean it. What is the best way to clean something like this without damaging it? I lightly scrubbed the back off to see the writing and it says WATERBURY BUTTON CO. Conn. I did an internet search and see that this company has been making military button since 1812. I don't think that this is that old, but does someone else know the era that it is from? I also found this bullet, which is the first of this kind that I have found. I see them on the relic forum and for folks in the south that are hunting civil war sites. Can anyone tell me if this is an old bullet? Thankyou all for helping out and happy hunting!
