Selling shares held in DRS

When I was younger I had a relative that thought giving me single starter shares so I can DRIP them would be a good idea. However, apart from a couple of them, I never really did anything with them. The result is I had many stock certificates of 1 share. I converted them to DRS for deposit to a broker as I was hoping to just get rid of them eventually.

Unfortunately, Wealthsimple does not accept transfers under $500 and Questrade charges $300 to deposit certificate/DRS shares.

Any suggestions on what I can do? I also tried donating the shares, but I guess they don't want these single shares either and they just stopped responding to me after I gave them the list of securities and estimated values!
