The knife is a Queen slimline trapper that I was offered in trade by a member here a few years ago. The tang stamp was used from 1932-1955. I like the knife a lot more than I thought I would; and, accordingly, I carry it often...though I admit that I consider its age and value (to me) when using it.
The coin is an 1838 Coronet (Matron head) large cent. My friends at Google told me it was
issued by the United States Mint in Philadelphia from 1816 until 1839. There are two similar designs of the Coronet large cent, the Matron Head and the Braided Hair
Here's a Braided Hair, produced from 1839-1857, for comparison
