Here is my latest copper Bullion pickup. I like the 1 ounce rounds and they are very inexpensive so it's easy to collect them. Hopefully I get around to organizing them one day. This is the Pledge of Allegiance.
I have a few of these and I quite like them. I have one that shows the obverse of a mercury dime that I like to carry with me as a pocket piece along a 1972 Eisenhower dollar!
Best wishes on completing your Canadian set. Copper is cheap so not like it's going to cost you a fortune in the future.
I bought some of the Zombucks series in both copper and silver. Looking at this pix from the web, not sure I bought them all. Just found them interesting.
