Yes I have posted alot of my finds on the indian artifact site, the first one I found 20 years ago was sort of warped, this one lays flatter on a table but still has some warp to it, pretty much the same thickness through. If it wasent for where I had found these things they mighta of been chucked in a box of odd stuff found. but these were found on a site over lookin the missippi river on the bluffs, and I have a ton of nice finds from this place (my back yard) Im hopein one of ya all can find something that even comes close (pic) to truly disprove Native relic, remember now that modern man still cant figure out how they built the piramids and mound citys with such deadly accurate mesurements thousands of years ago. so it being "too perfect" dont sway me on the modern thing, if its modern theres got to be another one just like it somewhere right?
