So I'm fairly new to coin collecting as a hobby and I've come across a strange 1964 nickel coin error I have never seen before and all the research I've done hasn't mentioned anything about this. The N in CANADA on the beaver side of the coin (can never remember which sides are obv or rev to save my life) looks like its missing or worn out. But its like there like it left an imprint or something? Any information on this is super helpful thank you :)
Also, if held in the right light I believe there is an extra water line mark and looks like the queens whistling on the other side but onky if held in that certain light to catch it. The missing N is what initially caught my attention to even look into this quite so thoroughly as I've said before I've never seen this before. There is no wear in any other letters or I might have thought it was rubbed off it honestly looks like it was a sticker or something that got peeled off and just left the residue
Also, trying to upload a picture of it but can't seem to crop it to being below 310 kb...
