Canadian 1964 1 Cent - Dot?

Tl;dr. Is this a 1964 1 cent "dot", if so what condition is it and what's it's estimated worth and demand?

I'm in my late 50s and recently retrieved my coin collection from the 1970s from when I was a teenager. So of course it's just a bunch of coins I found in spare change, mostly. It's been in a safety deposit box since about 1980 with my parents. I've been living abroad since then, and now back in Canada.
I have been going through them with the firm knowledge that almost all of them will be worthless. However, I was happily surprised to find that I amassed a couple of dozen pennies and nickels that I bought direct from the local town coin shops (Bill Foote's Coin and Stamp in Langley BC. and the Vancouver coin shop that I think was on/near Seymour St.)
So I have these "brilliant uncirculated" ("B.U.") nickels and pennies in 2x2 cardboard holders and, using an online guide at coinsandcanada.com as a guide, have been going through each "B.U." coin to check for worth.

Them I came across this. A boring 1964 1 cent sold to me in about 1979 as "B.U.", for the fee of 10 cents. But when I looked at it more closely against any of the known variations, I found a small dot exactly in the right location. According to http://www.coinsandcanada.com/coins...nt-1953-1964 I was reading, a 1964 "dot" is pretty valuable. However, the few photos I found online of this variation seem to show a larger dot than mine.
I've removed the coin from its holder and taken photos of it by rotating it in position so that the sun illuminates it from multiple sides. I've included photos of the other side to help get an idea of its condition. I'm not naive in believing that the "B.U." grading I paid for back in the 70's means anything nowadays.
I'm old enough to not get too excited about this "find" so I'll await the group consensus before popping corks.
Feedback on confirmation, grading, likely interest etc would be much appreciated.
And yes, this is my first post here. But I was collecting coins in the mid 70s so hopefully I get a tiny bit of credit for that!
