1943 Tombac Error - Struck Through?

It looks more like a lamination flaw to me.

I have a penny that looks very similar. Foreign object on die maybe?

Good point Crazyb0. If it were struck-through, the weight should be normal. A peeled lamination will have missing original metal and should weigh less than normal, especially with one that large.

What is the weight?

If this were a US coin, I'd consider the value added to be minimal at best and nonexistent at worst. Too common, too random. However, not being Canadian, I don't know how it would be perceived at home.

SSP, I just noticed what seems to be on the OP's coin a planchet alloy problem similar to our "woodies". Or is that just a funky staining? It seems to have minor streaking to right of bust and then left of V. That would indicate improper mixing/separation of alloy ingredients. Further explanation of lam troubles and causes of die faults, Just a maybe...never heard mention of a Canadian Woodie before...?

Crazyb0-
Is this not considered a Woodie?
There are a fair number of Canadian Woodies
especially in the earlier years

Ace, I consider error coins such as the "woodie" as just poor mint quality controls, not necessarily a mechanical (or human) malfunction like a clipped planchet or brockages. I would have expected you Canucks to have gone absolutely crazy over the "woodie" like you do over all those "variety within species" versions you've labelled "gotta have to complete a series" varieties!

All seriousness aside,...yes the "woodie" here has been debated as to exactly what it it caused by. No solid consensus has been given to my knowledge exactly what had caused the lighter streaks in LWCs, the early years here being more prevalent as well as JimmyD has stated about the early Canadian coins. My thinking falls now after this, to think it was just an unfortunate problem of mixing the alloys and that the assumption that the yellow is nothing more than an incomplete smelting of brass pieces added to the individual run mix. Since these coins are actually a mix(alloy), copper and zinc making a bronze, addition of brass (higher zinc content bronze) if not heated long enough while turning the vat, could well have caused this in the early days of production. Newer forms of smelting introduced in 20th century, allied with better ingredients produced better stock. (You dont think Papa John's invented this idea, do you?). I do find it intriguing about the Tombac mixes, same reason US has "steelies", needed the base metal for bullets, production was rushed and QC levels were ignored to rush products out he door. Hence the errors on the Tombacs. Neat!

After relooking at JimmyDs pictured coin,the coin shown is NOT an alloy woodie. If you notice the fields around the devices are lighter than within the details (N & 08). This is just rubbing wear, not alloy.
