We would not buy in bulk as we did with the foxwood gaming tokens, unless well below spot value. Yup.agreed to a certain extent by all means. Trust me, I know from personal experience with these.
They are very difficult to unload because of the odd dimensions and the cost of pulling them apart to melt down.
You should only pay well below spot for them.
Unless you have ones with collector value, I would stay far away from these.
