Found this one last night. I think these are tooling marks in front of the queens face but I would like an experts opinion. Thanks  |

I don't think they are tooling marks.
My guess is that very tiny chips of metal (die damage) have spalled off the hardened die along the edge line of the Queen's face.
The gaps left behind have provided tiny gateways for metal to flow through, when the coin was struck (pressed).
I think that 'press' is a better term to use here, because it allows for a tiny amount of time for the metal to flow.

Coins&Canada has a pic of it listed as die damage but no other info, here's a close up. It looks similar to a nickel SPP-Ottawa had posted a while back .. 300929242186 ..looks very similar. thanks for your comments 1994  |

This phenomena was written up in the CN Journal, July/August 2012, in Henry Nienhuis' column, Oops! Error of the Month...
They are definitely not Trail Dies (trailing marks).
I don't necessarily agree that they are tool marks, one hypothesis is that these were cause by light feeder finger scrapes on the production dies, as the coin was being produced...

Thanks SPP
I think I may have overlooked this type of error a few times but it stands out on a good coin and I'll be watching for more.

You see the exact same feature on 1994 to 1996 5c, 25c and 50c coins...

I have this flaw on the 1996 5 cent coin twice. Nice to see it on a cent.

A similar phenomena is with the George IV FIVE CENTS.
Hans Zoell monikered the term 'spikes' to identify these.

I think Feeder Mechanism Damage to the die.

They are called SPIKES---and also appear on USA coins---check out the Numismatic Dictionary above.
