Hardy har har.He's talking Canadian. I beleive that the reason for Yank coinage having denticles is so that the coins can't be shaved.The faking is a good reason but fake coinage can have dentacles.Antway, he was refering to the dots around the rim.

The reading on the edge is to stop shaving.

Charlton guide states they are "...used to prevent the punch from spreading during repeated die sinking." (p.410)
Funny to see all the different answers from the "experts".

Here's the thing, most of these devices are put in place for one reason when they start and later on someone realizes they actually may have other advantages. So microwaves were initially being researched as a form of communication and then someone realized "hey I can excite the water molecules in food and cook it". So all the answers are correct to some degree, but I'm willing to bet the first guy who put the first denticles on a coin didn't leave a written FAQ behind.  |

lol... everyone agrees what they ARE. What they are FOR seems to change over time, probably in ways the original designer never thought of or maybe the designer did know all the uses and denticles are a brilliant idea that goes mostly unnoticed today.

Sorry folks, I guess most of you are sick of this thread, but I need to add an update. For those of you who are Royal Canadian Numismatic Members, please have a look within this Junes CN Journal you should have recently received on pages 273 and 274, 'Anatomy of a Coin'. Well, they are advising that the purpose of beading is as such.... "Beading actually has a technical purpose, in that it helps avoid flow lines which result from the flow of the metal during striking" This contradicts other offical statement, including the one I received right from the RCM.

Dollar1948: You should write an article. Collect up the references, get some pictures of shaved coins etc. Sure it could be published in a magazine.

Its amazing the contradiction in info I'm getting depending on what source.
I just look at my entire Canadian collection, and the coins dating back since 1858 has got them.
You'd think because someone has to engrave those things on the die, plaster cast, (what ever) since those days and because they are so intricate, that the genuine purpose must be well known.
