I tend to find these on occasion, most are embedded by the collar die into the reeding and rim, but occasionally, you see flakes and fragments of copper struck right into the nickel. Not super scarce, but not common either...

Neat.
Does this occur with other denominations?
How does the contamination occur?
Have you/can you determine the nature of the flakes? Copper or penny bronze?

I cannot speak for other denominations, except for small cents (which is moot when it comes to copper flakes)...
Unsure of the composition. I suppose I could take it into work and put it under the SEM...

Hi dialogue_gvf
I know of at least one other denomination with this cross-contamination flaking - I have a 1967 penny with a silverish flake in it. It's possible that it's an actual silver flake, given the year, but that's not a for sure as we were also minting nickels, and any coins that we minted for other countries used different alloys as well.

Here is a 1992 Alberta 25c with embedded scrap. I think it's a fragment of copper.   |

Most Off-Metal flakes hitch-hike a ride on planchets that are processed from out of tubs that also carried copper blanks and/or planets in an earlier operation. In effect, most tubs will have various flakes within.

To dust off an old thread... I found a couple more in a recent search. I usually sell the small ones, but these two are larger than normal, and of course, keepers! This one is on the reverse of a 1975 dollar  This one is on the obverse of a 1980 dollar (almost like the Queen is wearing an ascot).

Here is another one in my collection, on the reverse of a 1974 dollar.
