I am the only one awake on Stamp Community. I have total control. ha ha haaa
Sorry,got carried away. North America is asleep and Australia hasn't woken up yet.
Here is a link to
ebay ca searching for 'canada duck'
https://goscf.com/t/12625Also look at the completed listings.
I would use
ebay. Read up on a few, find a site or two that talks about the,. List them singley of as a collection like that one listing ongoing now.
If too much time and trouble then depending on how close you are to a stamp show or store, a dealer would buy them, but not for face value, probably for 10-25% of catalogue value if they are in good condition.
What you need is a collector of these that would pay half catalogue value and feel he was getting a deal.
By the way, to sell on here Stamp Community, you need 50 posts. If you're just selling them
ebay or some other site like Bidstart or Wensy or Delcampe or others.
