I have had more problems with sellers in the USA than anyone overseas. In fact I have had no problems with overseas sellers. I buy mostly from Ukraine or Russia now, usually not coins though - usually music, art etc. My more interesting purchases have been from countries like Indonesia, Hong Kong, China etc, but everything arrived just fine and I was a pleased camper with the goods and shipping. I do buy banknotes from a seller in Thailand about 3-4 times a year, he prices stuff fairly and ships securely and I have gotten very nice stuff otherwise difficult to find.
