Similarly, you see similar stripes from rolling blank strips with woodgrain toning (both sides are always parallel).

M_d_in_guy Pillar of the Community Canada 1049 Posts	Posted 01/22/2015 02:38 am these coins have seen quite a few years in water, with it flowing over them non stop, I'm thinking in a river sitting in a small group of pebble on bedrock. Very similar to what I have detected (nickel coins) in the rivers over the years. The ones at the water line in sand or pebble don't seem to have linear corrosion as do the ones found in the currents. IMO. Report this Post to the Staff
