Got 10 rolls of pennies from the bank today and in the 8th roll this showed up.... Not sure what to make of it....  ..BUT I'm hoping its a mint error... It looks like a penny in a collar...  ..Mint Collar. .. Dime Collar. Because of the raised rim there are hardy any scratch marks on this coin.. Also along the outer edge it is half and half copper and silver..       Edited by D

Yup, spooner. Looks just like the ones my grandkids tap on until they're 1/4 inch thick.

are you guys for real?
spooner coin? this coin is NOT damaged. This coin is perfect...
Look at it with interest and see the details..
There is NO way a spooner coin could survive without damage....
next thing is that someone is going to suggest a Chinese fake, for lack of something else to say, right ?

2005 Copper plated zinc should weigh 2.25g - this one is heavier. Hummm.
Zinc (silver gray appearance) I think is what we are seeing on the edge but where is the extra weight coming from? Certainly not a dime collar (18.03 mm).
I don't know.

that's weird, 2.5 should go up, not down

Interesting rule of rounding up/down: Round half to evenA tie-breaking rule that is even less biased is round half to even, namely If the fraction of y is 0.5, then q is the even integer nearest to y. Thus, for example, +23.5 becomes +24, +22.5 becomes +22, -22.5 becomes -22, and -23.5 becomes -24. This variant of the round-to-nearest method is also called unbiased rounding, convergent rounding, statistician's rounding, Dutch rounding, Gaussian rounding, or bankers' rounding. For most reasonable distributions of y values, the expected (average) value of the rounded numbers is essentially the same as that of the original numbers, even if the latter are all positive (or all negative). This is widely used in bookkeeping. http://en.wikipedia.org/wiki/Roundi...half_to_even |

Why so hostile hhbkiddo?  Not hostile at all. Just very dissappointed.  It seems every time someone has an unusual coin, the comments go negative first. If that does not work... interest is lost, and often, very often, the actual questions and concerns a poster has are NOT properly answered or dealt with because someone just simply has to 'overtrump" the post with another sometimes not even related issue. There are subjects on this forum which are highly interesting. Most of these subjects are dropped, sort of"peter out" without getting the attention they deserve.  WHY is that? I have asked my self many times that very same question. Perhaps there is the underlying jealousy say "why can't I not find a coin like that" or something similar. Or, who know why. There are, unfortunately, very few members who really actually do appreciate the real Canadian Coinage. These members know who they are. The rest seems to fully subscribe to the pink butterflies, yellow snakes and green thunders on the quarters which perhaps have a "mint induced" error to boot. ...Tunnel vision.  do you really think today's very hi tech minting process and its quality control allows for soooooo many accidental "errors", compared to 20 years ago? Well, if you guys do, I have 1000' of white sand oceanfront property for sale for a million bucks in Alberta.  However, these "errors" seem to get all the ATTENTION., while the real thing gets very little. beats me.... and many others... Go ahead and crucify me now for being unconsidered ... I am tall and have at hick skin... A sad, very, very sad fact!! |

I'm going with spooner as well. By whatever means - banging, spinning...
I think the copper plating not following the trauma is pretty strong evidence.
Weight is within spec.
JMO - and would rather have an error here but alas.

I kind of agree with you. Though for this particular post I found the weight a bit odd - but my theory got whacked pretty quickly. Oh well.
