I have saved hundreds of them so far.
They chip easy & I don't think they are AlNiCo, simply because they don't have the chrome plating on them, could be wrong, dunno 100%.
I think Ebay could be a good way to sell them, some people don't really have a way to get a lot of them.
$2 a magnet & its getting close to what you make off the copper.
As they are so strong they get used in projects & stuff, making electricitys a good project.
The permanent magnets in the smartdrive motors can be replaced by the stronger magnets to make more power from the same parts.
Best 'Ferrous detector' ever. I have painted some & given them to the scrappers when I go to sell my metal, they love them.
