New federal laws make it illegal to sell any elephant ivory object across state lines, ebay isn't the only place it is banned. All sales of elephant ivory are banned in CA and the trend is spreading to other states. These ridiculous laws include antique ivory, although it is supposed to be exempt in some states proof of age is on the seller, and ivory cannot be physically dated without great expense, and only if it is old enough for carbon 14 testing such as mammoth ivory. I have always liked ivory objects but government regulations are making it worthless as far as selling goes.
