As the title reads, I am trying to confirm that the dime below is of the shoulder strap/fold variety. I did a bit of searching and found some information, though some of it was less than clear. So if anyone who is knowledgeable about Canadian coins could chime in and maybe educate me a bit more, that would be great.
The "shoulder fold" is like a bra strap on the Queen .. I guess the strap on a dress or gown in this case. It appears that yours has one. On the "shoulder fold" examples, the ends of the I's (like Dei) are not as flared as the no shoulder fold. Other dates and other denominations have different markers. My personal opinion is that there really weren't two different punches that made the working dies .. only one that got worn so that the working dies later on in the mintage cycle has less definition.
The most important marker, and easiest to see is the I in DEI. You need to look at the ends on the I, do they look like this "I" or like this "l" and looking along the length of the I does it point at a denticle or between two. Grab a Charlton guide and identify the coin. Shoulder fold / no shoulder fold rarity varies between the denominations.
