Looking for Canadian large cents and variants of small cents

Looking for:
- Canada large 1 cents in high grades
- Canada small cents 1920-1949 in high grades
- Canada small cents - all kind of variants and errors (double, hanging, extra spikes, harp, etc)
- all Newfoundlands 1 cents in high grades
- all pre-Confederation coins in high grades

Swap for my coins only, sorry but I don't buy any coins.
