I have noticed a re-occurrence of incomplete beads on later Canadian coins.
It seem to me that it is more pronounced in some years and denominations in particular;
I was going through some of my coins (which have yet to be properly sorted) and believe that I have a good hand full of 2016 nickels which have beads missing or ghosting in alternating spots.
Surely someone else has come across this?
It seems as though this is much more common of late, and I was wondering if any years have these as a recognized variant.
I did a search of this before creating this 'discussion' and couldn't find a thread quite like this - but instead they were often one-off examples, an mostly it was mentioned for quarters.
Thanks in advance for offering input :)

I think that the quality control at the RCM leaves alot to be desired in the last 10 years. Usually what you are talking about is"struckthru grease" but, unless everyone there is carrying a caulk gun, that seems strange. I was thinking .... just a thought that they don't have the dies exactly parallel to one another, maybe off by a degree or so, making some strikes very full and the 180 weak .... just a thought, maybe way off base for the mint, but I've sure seen it in machine shops. |

I was really hoping that someone here would be able to speak up without having to pander to the forum-typical "post a picture"; This is very tough to capture on camera for someone like me who is not setup for this type of photography. This is why I tried to explain what I was seeing, and asked if anyone else noticed (a re-occurrence of) this - as opposed to this issue being isolated to the 2016 minted coins. Hopefully the attachment works so that some of you can see it.  Edited by unruhjonny

I might add, that I have had these since 2016 or maybe 2017 - so these were pretty new;
If my memory serves me I was looking through change that my mother-in-law had at her place and one happened to catch my eye, so I put aside all the 2016's that had this.
This was NOT an exhaustive search of any kind.

? Nothing is catching my eye here.
Just exactly what are we supposed to be comparing in this pic?

He's referring to the rim beads, they are missing some of the small beads around the inside rim. This is quite common. The flow of metal is to the outside of the coin so it could be it starved for copper from insufficient pressure. Or probably just small amounts of grease and other debris can get pushed to the outside of the die accumulating in the recesses on the die. Those beads are so small It doesn't take much to fill the recesses on the die that makes them. Here's a crop from the picture above that may help.  |

Plugged die holes ? Do any coins have a matching pattern of missing beads ?

Thanks Chad for the better close ups;
This is why I refer to some beads as "ghosted" - they're not really there, but theres almost a shadow of them - so you can see they were on the die.
That 2015 is neat;
I might do some more coin roll hunting, and look for that.
Terry, with my small sample size, I didn't immediately notice coins with the same bead issues - it seemed like they were random - some 2016's looked fine, but most had this in various combinations.
