I'm not trying to hijack the thread since this is important for these type coins. What's the best way to halt the corrosion on early copper? Can corrosion continue even after it's been slabbed?

Those are great questions. You can halt and stabilize corrosion by applying Verdi-Care on your coin. https://verdi.care/?srsltid=AfmBOoq...3U62lAUjqmJz Since slabs aren't airtight, corrosion can continue, especially if it's not stored properly in a good environment.
