Canadian Or US Copper

[ktonva]

My question is if you can find Canadian is it a better plan to get it as the metal percentage is higher. (modern coins)

1982–1996 2.5 g 19.1 mm, 12-sided 98% copper, 1.75% tin, 0.25% zinc

Yes. But it's a big "if".

Curious why the US portion of your chart begins with 1962

Adjusted numbers.

I sorted two bags of cents a week or so ago and got just a little over 1% Canadian copper. If I could sort 100 bags a week I would have something.

You could keep both the US and the CA copper cents.....I do. The CA coppers cents go into a 1 qt potato salad container and the US cents go into bank 25$ boxes, coffee containers, 50 cal ammo cans, 50$ bank poly bags, 5 gallon "homer" buckets and 30 and 55 gallon steel open head drums not to mention the ones on the floor in the corners under the cabinets.
