I thought about that also Mike, especially when I first saw it. But if I took a close up of it, you would see that it was manufactured "intentionally" that way. It is way to smooth and precise to have been a file at one time. "Dinging spoon" (slapping spoon) it may be? Manufactured as a slapping spoon? IMHO the edges are too sharp to slap with. If you struck the material a little "off square," it would cut into the metal. I'm still researching the Mound Company.
