I kind of have a thing for coins with cool edges, here are a few of mine. Dated. "Waffle" I think this is called a "rope" edge. I think this is called "reeded". Abbreviations... "FERT" is explained here. https://en.wikipedia.org/wiki/FERT Feel free to post any coins with cool edges!
here's another abbreviation... "RMB" This stand for "Renminbi" https://en.wikipedia.org/wiki/Renminbi this coin has a little message.... "Payable in Anglessy London or Liverpool"
If you want to spend less on a coin with pretty much the same edge style, get any €2 coin. These are the edge types we use, from 1 cent (top) to 2 euro (bottom): (Image: code-knacker.de) Christian
