On the copper 43. PCGS reported https://www.pcgs.com/news/pcgs-certified-1943-d-bronze-cent-sold-for-17-million "The anonymous collector who formerly owned the coin "donated it to a charitable organization so they could sell it with all of the proceeds going to the charity," according to Andy Skrabalak of Angel Dee's Coins and Collectibles in Woodbridge, Virginia who acted as agent on behalf of the former owner." I think much of the price was going to the charity and possibly ( with a good lawyer ) could be tax deductible . At least that's what I would do. Most estimates for any others is significantly lower. IMO, Jim
