I am assuming that all coins are US coins (or facsimiles thereof)
1. The reeding is evenly spaced and clean bumps,humps, and scratches. The reeds are spaced very far apart. I am not aware of any US coins that have reeding that matches this.
2. The reeding is shallow, ill defined and rife with lines that look like file lines.
3. The reeds are not even and show extreme inconsistency in shape, form, width and depth with many unilateral lines and scratches
4. The depth looks to be consistent and fairly clean the reeds are not all exactly the same width. This looks much like the reeding I have seen on quarters.
5. The reeds are overly narrow and wide spaced. The Valleys between the reeds look to be deeper in the center than on the ends as if cut with a wheel such as a Dremel cutting wheel.
6. Every cast coin I have seen has an appearance like this.
I think number 4 is the only genuine edge.
