I came across this site in a search for a Canadian bill value so I thought it would be worth seeing if I could get some help here. I used to be big into collecting currency as a child and recently found my old collection and I was going through some of the bills and I came across a 1973 Canadian dollar bill but I cannot find any guide or reference to the prefix on the serial number nor any others with the same prefix. Maybe its a special one or maybe I am not used to Canadian numbers but the prefix is 3 letters (BAC) the entire number is BAC3569606 and it is in absolutely perfect condition. Any help with valuing this is appreciated. I don't care if it is worth 1$ or a million dollars, curiosity has me now more then anything.

Thank you all for your help.
