With out a weight, weak strike or thin planchet remain as 2 possible explanations.

Please disregard my grammar from the last post as huked on foniks werked for mi. Ok. With that being said, I weighed, not weighted the coin tonight and it weighs 4.46 g as opposed to 4.54 grams which it is supposed to I think. So a difference of .008 grams. Is this enough to make it a thin planchet?

Just wondering if the weight is enough to make a difference?

I have been calculating Canadian coin weight of used coins and your 1962 nickel should weight on average 4.545 grams.

Thanks wert. .008 of a gram isn't alot of difference. I was hoping that nickesguy might be able to tell me if that's a significant amount....

Mint tolerances for planchet weights are quite broad and forgiving. It depends on the rolling of the strips, the density of the alloy, all of which have to have some variance. I have seen coins vary as much as 0.2 of a gram from a mint bag. I think what you have is a weak strike.

I agree with SPP. Probable weak strike. Nice coin.

There are quite a few of these 5ยข from the early 1960's. Hans Zoell calls them a "Bald Beaver" variety. For example, Hans Zoell #Y193q & Y193x from 1961 and #Y195x from 1963. His descriptions call it the "Result of a badly filled die."
These coins have an weird look though for a filled die error. I'm going with an Annealing Error for this one. The error seems to oddly affect just the central portion of the coin. If a planchet is too hard, it won't strike up well in the deeper portions of the design. In a sense it might be considered a variety of weak strike, though the press may have been set up to strike well with a normal (soft) planchet. ~ JFK ~
