Altaira Pillar of the Community Canada 2523 Posts	Posted 01/06/2015 10:53 pm If there was something on one of the dies, the other side of the coin will be well-struck. There shouldn't be any bending of the coin. Also, the more obstruction there is on the die face, the stronger the rims and unobstructed devices will be. Doesn't look like it's the case with this coin. Report this Post to the Staff
denny7000 Pillar of the Community Canada 1018 Posts	Posted 01/06/2015 11:27 pm Thanks to all who have posted an opinion so far, I am more perplexed than ever now. It seems I may have a unique coin. I have looked at both sides of the coin now more than any other I have. I need a break, off to play poker online. Thanks again. Report this Post to the Staff

SPP-Ottawa Moderator Canada 10464 Posts	Posted 01/07/2015 09:47 am I see three things here: the planchet was flawed prior to the rolling mill, the dovetailing of the rims shows that the rolling mill (which creates the rim) probably caused a partial lamination, a weaker spot at the edge of the coin would create a small Blakesley Effect the coin was then struck, and the lamination detached itself sometime after the coin was struck, the weak spot on the rim was subjected to post-mint damage, possibly from rolling machines One question, have you weighed the coin?

denny7000 Pillar of the Community Canada 1018 Posts	Posted 01/07/2015 1:37 pm No at this point I no longer have a digital scale available so I haven't weighed this coin. So this is a flawed planchet creating a blakesly effect and a subsequent delamination after striking. Report this Post to the Staff
