Thanks Will
It is very nice to be remembered.
But since I am not a historian nor art researcher
I would still like to share my shabby experiences on ancient culture erdos with some examples

the first example is a bone goat? head which I got several years ago in the city Xian shannxi prov. I believe it's from the north part of the province where used to be the border between Han and Hun people.and this piece belongs to the Hun people,so called erdos culture.
you can see the green color and patina on the bone surface
compared with the so called dice beads posted by Lynne
the big difference is the status of the bone itself. you can imagine the differences of bones of the age 2000 years and 100 years.

the second are some outstanding gold pieces of erdos culture from chinese museums. one is the famous crown found in innermogolia in 1960s. the other is a wonderful belt ornament in shape of a horse.
(C.T.Loo had published a book about ancient chinese bronze wares in 1920's most of the collections in his book are from erdos culture)
To me erdos is a culture of metal with very unique and impressive design of its daily uesd objects. the representational way of expression of fierce and temperate animals and designs have strong influence to Han arts and arts of other nomadic peoples like Donghu of the same age and later Xianbei.

the third is my recent acquisition from Ningxia prov. some gold pieces in the shape of cutted shell which I believe they were uesd by Huns as ornaments . this kind of thing started very early even before the time of Hun people and probably uesd as money at the very beginning.
the gold one is very rare and obviously it is the imitation of the real shell one.Both are of the same time.

at last the two beads bronze piece from Will is wonderful
I like it very much.
thanks you all
