Are copper pots pure copper or copper coated aluminum?
Old (antique) copper pots and kettles were commonly of tin plated copper. Copper is relatively heavy and expensive so nowadays it is often supplied in combination with thin stainless steel on the inside and an aluminium base layer between. Stainless, by the way, is easy to keep clean, imparts a hygenic impression and reacts very little with food. First the copper then the aluminium serve to spread the heat evenly over the base so that there are no hot spots on the stainless. Nevertheless the copper mainly serves the aesthetics and it's common to have stainless on the outside of the base with a sandwiched layer of aluminium to do the heat spreading job.

Don''t know where you are getting hundreds of dollars for a pot If charging that much they had better be huge or pure copper, which is currently very costly. Traditional old cooking pots that look like copper are solid copper. Some pots with copper inside are that way to enhance chemical reactions in mixing and cooking. Much more common that copper plated on aluminum in my experience are copper or aluminum plated on stainless steel - which is much harder to stand up to stirring and corrosive fluids but much less conductive.
A thin layer of copper was welded outside the bottom pot. Copper is more expensive than aluminum,there was how the manufacture cut cost. Besides, pure copper make cooking pot is not good for human health.
