I had a 40 centavos 1915 Cuba coin for sale on
ebay and it was up for 2 weeks or so, but
ebay just sent me a notice the listing was cancelled because of the "Embargoed goods policy." The coin was listed as 40 centavos Patria & Libertad.
My understanding is that SAP is correct when he stated: "Pretty much anyone off-eBay will happily sell you pre-revolution coinage, since they're not covered by the US trade embargo."
It seems odd to me how diligent
ebay is in blocking sales of legitimate listings, while they don't seem to have concerns about all the fake coins sold out of China. I just did a search for 8 reales closed listings, and the number of fake 8 reales sold is sad. And sometimes the price gets bid up to a level as though the coin was real. At least they appear to have blocked the guy selling out of Poland who had dozens and dozens of fake coins. He would sell until he was cancelled in one ID, and then just get another.
