eBay has listings for post-1962 coins (there is a listing for a 1971 coin and a 1993 coin), as well as some pre-1962 coins. The article made it sound like they would ban all listings because a pre-1962 would be illegal under the embargo if it were removed from Cuba after 1962.

I have always relied on coin shows in Canada (where the embargo does not apply) and Florida to get Cuban coins and currency for my collection.
