Robert, I have received quite a couple of emails already, and I have reserved several of the chips. There are however types where I have more than one chip available. I could compile, say, a collection of 25 different chips from Botswana, Namibia, Zimbabwe and South Africa, for US$ 60 plus US$ 15 for registered airmail. Total thus US$ 75, if you are interested. Another option would be to exclude some of the larger denominations, then I can probably send 20 different chips for around US$ 50 incl. shipping.
