I am far away from being an expert, but thanks to this forum I detected a counterfeit in my collection. And I am seeing some similiarity with what other people told me, and is that there are some things that look bolder in your photos than the ones I am able to find online. That to me means that it was made from a cast mold.
What calls more my attention is the date, in yours looks bold while also has wear, so doesn't match in my modest opinion.
Again, I am no expert at all and just reviewed it with things online. Hope someone with more experience could share their thoughts!
For anyone interested, I made a video under microscope for the beautiful Canadian set I got! You can watch it here:
I am intrigued now to compare the bimetallic 2 dollars, the center seems a bit misaligned, don't know if that is normal. And also, in the one dollar coin, seems to be some damage between OLL (from dollar)
Sorry about the quality, tried to clean the plastic as much as I could! Focusing different heights was hard
