Good to know!First of all, do not mix the edge and rim of a coin.

The edge is the outer part of a coin and extends over the entire circumference of it. It can help to identify a coin (also for the blind people) but can also help to know if the coin itself is genuine.

The rim is a raised border (sometimes dotted) on both sides of a coin, also called "listel" in French. It protects the pattern engraved on the piece against wear. It is possible to find coins with no rim (like some ancient coins).
