Do used zinc anodes (from boats or water heaters) have scrap value, even partially corroded?
Short answer: Yes, though a used anode has already lost material to its intended sacrificial corrosion process, so its scrap weight and value is naturally lower than a new one — a genuinely worn-down anode still retains recoverable zinc value, and it's worth selling rather than discarding, just don't expect full original weight or price.

Zinc anodes are deliberately designed to corrode sacrificially, protecting more critical metal components (a boat hull, water heater tank) from corrosion instead — by design, a used anode has lost some of its original zinc mass to this protective process.
Why it still has scrap value
Whatever zinc mass remains after the anode has done its job is still genuine, recoverable zinc scrap — it’s simply less weight than when the anode was new, which proportionally reduces (but doesn’t eliminate) its value.
Practical selling notes
Accumulate several used anodes if you replace them regularly (common for boat owners) rather than selling one at a time, and remove any attached fasteners or mounting hardware that isn’t zinc before selling, since these can be a different metal.
How ScrapTrade Makes This Easier
ScrapTrade lets you list accumulated used anodes and other zinc scrap together, making even naturally reduced-weight material worth the effort of selling.
