Old Canadian Bills From Over The Years

The Dominion of Canada (DOC) $2 (DC-26j) is the most promising note you've posted. You should put it in a large currency sleeve & try to keep it in a dry protected place. It would helpful if you posted both front & back images of this 1923 Issue since that would give us a better idea of condition, but from what I can see it's likely about F (Fine) condition (with the edge tears on bottom border) which should fetch around $100 -$130. The 25 Cent "shinplasters" look pretty nice too. In the future, you need to post the reverse image of the $2 for the serial number.
