I have found 1968 silver coins that have "Philadelphia" reeding also. I am wondering if a similar collar that we use to identify the "Philadelphia" 1968 10 cent coins also got installed in Ottawa at some point in 1968/69? I don't know enough about the minting process..... do collars get replaced with some regularity? If so this might explain both the 1968 silver and 1969 nickel "Philadelphia" coins.

1968 was the only year that I know of with different edge grooves.
You should get a bunch of 69's and compare all the edges.

Jim0815 I have both in mint condition. I am talking about the 1969 canadian 10 cent coin. I have both as well as you do. if you want I will cut them out of the plastics. then I will photograph the 2 coins for you showing. the two different types of reeding. other wise you have a new variety

mcschilling, living in the lower 48 I really don't get to see many Canadian coins. Rocky, that is most kind of you to offer that. I wouldn't want you to do that.

Is it just me, or does the difference in reeding appearance seem to be simply caused by a lower strike pressure on the Ottawa coins. Surely, the collar would have been standard like the dies and planchets used. A slightly higher strike pressure in Philly may account for the fuller reeding.

That is a really good question Spruett. I think sometime today I am going to be emailing some people at NCG and PCGS.

Jim/John,
Just FYI the supposed distinguishing characteristic between Ottawa and Philadelphia 10 cent coins is that those from Ottawa are supposed to have V-shaped grooves on the edge while those from Philadelphia have a flat bottom. This is as shown in McShilling's photo above. If you look at a large number of Canadian 10 cent coins, the two types are obviously different. At the same time, you do see variations among the V-shaped coins that could be caused by changes in strike pressure (i.e., in some cases like in McShilling's coin on the right above, the reeding does not go all the way to the top and bottom edges of the coin. In other cases, the reeding extends more fully to the edges.

Here are some of my lousy photos of silver 1968 coins side by side. Hopefully I have caught the light in one photo so as to make the difference obvious. Anyone have a US 1968 dime handy to compare with?   |
