Quote: "Sulfur"Canada, Colonial: the biggest problem with "British North America" is that this term encompasses more areas than just Canada. With that being said, those last two results you showed are specifically talking about the history of Canada, so while they are correct to mention that Canada was part of British North America, they can also understandably omit those places outside Canada that were also part of British North America. And so "Canada, Colonial" is generic enough to encompass the specific parts of British North America we are talking about, in my opinion. 
Altogether it doesn't matter a huge lot what it's called in Numista, but let me take this opportunity to say a couple of things with my historian's hat on (which I am ─ well ... not a
hat but a
historian). If we try to imagine ourselves in 1839, for example, we would have never considered New Brunswick as a Canadian colony. But it
was a BNA colony. What's more,
as said in Wikipedia, "the term British North America came to be used more consistently in connection with the provinces that would eventually form the Dominion of Canada, following the Report on the Affairs of British North America (1839), called the Durham Report". This is the very definition that explains why British lawyers themselves called "
British North America Act, 1867" the legislation that provided for the creation of the Dominion of Canada.
If you decide to go with BNA (again, it's entirely up to you), as it would be under Canada, it would be clear what definition is being used and it could be pointed out in the intro to that section what definition is being used (I could write it up, though the Wikipedia text is all that we would need).
As you know I'm sure, anachronism is a problem for the historian. Not long ago, I submitted a number of corrections to the French pages where Louis-Joseph-Napoléon Bonaparte was just called "Napoléon"
while he was President, not Emperor, i.e. for coins struck between December 2nd 1851 and December 2nd 1852, when he was crowned Emperor. Only from this later date can he be called "Napoléon". Likewise, Napoléon I was Napoléon Bonaparte, or just Bonaparte, before December 2nd 1804 when he was crowned (or rather crowned himself) Emperor.
I hope all this doesn't sound too much like a lecture!

I know many Numista users are aware of anachronism, but it looks to me like many more don't. I should point out that sometimes, even scholars commit (usually minor) anachronisms, so I wouldn't hold coin collectors to higher standards.
