"selling the magnets... to whom I have no idea" In those pre ceramic supermagnet days those were probably alnico magnets (aluminum, nickel, cobalt) and although you get $4/lb for scrap nickel you'll only get $1/lb or so for alnico magnets from a scrap metal dealer, today. Where you'd get your feedstock from is a complete mystery as the scam of "recycling" by shipping used electronic to the 3rd world is pretty modern. If you could get an infinite supply of gear (rejects returned to manufacturer?), I don't think it would be a challenge to rip apart speakers of that time and generate a roughly minimum wage income. Nickel is really quite valuable. Prices always vary but a tenth the cost of equal weight of silver is semi-stable-ish. Figure maybe a hundred times what you'll get for scrap steel. Or maybe two or three times what you'll get for copper. If there's precious metals, and semi-precious metals, I'd say nickel is just one step below the semi-precious, like wanna-be precious metal.
