Out of my collection:
divided core swirl
Size: 0.79 inches / 20mm
Condition: near mint- - original surface
made around 1900 in Thuringia, Germany
Registered and insured airmail postage from Switzerland is $17. Within Europe it is cheaper. Of course I will combine postage, I can send up to 15 regular marbles for the same postage.
If you have to pay right away I will refund the extra postage you get charged immediately.
Feel free to ask any questions :-)
