other halves of potato that had the mold on it

You could try dusting them with garden sulfur and see what happens. And you could grow the "off" ones in a container to make sure nothing bad gets started in your garden. I threw away (not composted) some unsafe-looking seed potatoes this year.

I would not do anythind. All you need eyes on seeds.
The seed will actually rot in the ground anyway. The starch in the seed is just food for the genes to nurish on while growing roots and stems.

Thanks for your input. Still haven't planted because there is still snow / ice on my planting area. I have been trying to clean it but there is still ice... also still probable freezing in the future
