Hi,

a very nice North American coin collector send me these two coins to be documented. I've read somewhere that there should be 148 denticles on the small denticle version, but I come to 149 EVERY time I count them, and I cannot find any I counted twice! I've attached first the general documentation and then a blow-up of the counting of the 149. Maybe somebody can tell me where I made an error?

I guess it would be important to find the source for the number 148...

An unidentified coin is a piece of metal. An identified coin is a piece of history.

I read something about this one time....If my memory servers me right and there is a 50% chance it will.

While Canada is a prolific producer of coins, there have been times for certain denominations where Canada actually
contracted for coins from somewhere else. 

It is my understanding that one was made in Philadelphia and one was made in Ottawa.
I would need to do some research to see if it was this year/series where that happened.

I think it was the 1968 dime...but maybe it happened in other denominations as well.

OK here is what I found:

From: A guide Book of Canadian Coins and Tokens 1st Edition, Published 2012 by James B Haxby.


" The caribu reverse returned to the twenty five cent coin in 1974, as did the large Portrait Obverse. A marginal increase in thickness in 1978 appears to be responsible for the creation of two varieties of reverse that year. The more common Small Denticles style has 148 shorter rim denticles; the scarcer Large Denticles variety has 120 longer denticles with Canada closer to the rim. "

In the same book for the 1968 dime, it lists two types
Philidelphia Reeding and Ottawa Reeding.

So that had to do with reading and nothing to do with denticles.....looks like my memory failed all the way around.

And all of that does nothing to help with an extra denticle.

From another group two more collectors have counted the denticles and guess what? Also 149 in both cases.... Can anyone here find one with 148?

I just recounted again, and it's still 120 and 149 beads, so numista is wrong and the source "A guide Book of Canadian Coins and Tokens 1st Edition, Published 2012 by James B Haxby" is equally wrong, since it's the source for Numista obviously!

For political reasons (my choice of the portable jpg format), I'm not allowed to make change requests to pages concerning Canadian coins in Numista, so numista will only be modified, if somebody from here can make the Change Request.
