Usually, .org turns me off a bit. But, these are almost suited to the .org extension because of their keywords. You can either develop them into minisites or try and find an end user. The only downside is that any action groups of charities that might want them aren't going to be loaded with cash. You might score low xxx though to the right person. I will add though, to a fellow domainer/reseller trade, these are regfee domains.
