Miniature bone Ca 1880 Doll's House Furniture

So I have googled the living day lights out of this and all the previous listed sights and auction houses say this in Bone/Ivory and they date from the late 1800's

do there is no damage but there are some spots which is apparently what happens with ivory over time. I know that overseas these things sell for a great deal of money but I'm not

sure about here in SA.

just for size reference the sewing table measures height 42mm width 44mm and depth 28mm

these have been very   Intricately carved beautifully carved and I believe they are of German design as these were my Mothers as a child.
