Welcome to the choir!
There is plenty of ivory, coral, tortoise ... seal and polar bear claws, baleen

that look credible and inexpensive. I'm not sure I want to know where the $0.2 cone shells come from either.
All in all, the ones I find disturbing are the tremendous amounts of probably new coral and ivory - hopefully fakes! Inasmuch as vintage objects are tradable nationally, and it isn't easy to tell which is what and where's going, the whole picture looks murky. Some sellers announce that they will enforce the export ban on ivory and coral and not ship across borders, but not everyone says and not all that say practice...
I believe that vintage tortoise is not banned from sale either and the chance of finding new material is slim because the source is all but gone, but I could be mistaking. The other types are rare and the objects appear to be from native hunting, which is permitted. Of course, there is no way to tell for certain.
What strykes me the most about all these materials are the low prices! With products from rare species sold at price points where quantity makes the day... things can't possibly be good. As if the bans did not detter commerce, not even pushed it to the underground, but keep the stuff way below the high end where scarcity can be priced. Makes no sense
