There are standard warnings that comes up for listing many things - original art works, things made of bone, military medals and uniforms - usually they just say IF things are such and such, you need to be aware of so and so.

 

If others seem to have no problem with listing such items, I would have a go. Use the same sort of wording and category as something similar (check current and completed items.)   I regularly ignore such warnings when I list things, as the warnings do not apply to my particular items (or at least I consider that they don't.) If you REALLY upset eBay, they will cancel the listing anyway.
