Coin edges
« on: February 25, 2014, 04:59:05 AM »
On the Internet I found the best, in my opinion, picture various edges of coins.

Anyone has a better picture of this?

Security edges and edge inscriptions are used as a safeguard against counterfeiting. Smooth edges and milled edges help the blind identify which coins they are holding. When were the first milled coins produced?

Also such edges helped prevent clipping

There are four fairly common kinds of edge missing from the first photo above:

- what I think of as the "Indian" security edge, as exemplified by various British India silver coins and modern 5 Re coins
- the fluted edge of the 20 eurocent coin
- the single groove of the 2 eurocent coin
- non-round coins.

There were also a number of coins issued in the early 19th century with milling in a groove - the 1806/7 penny, halfpenny and farthing of the UK are examples.

In that image most of the coins stack nicely on each other. Look in the bottom right....what is going on with that gap?
