These are a bit different, as they look like they originally came from Coach's Corner, and are now on Ebay (being sold as replicas). So it is perhaps the reverse scenario of those posted above.
Equally disturbing though, is that these could be purchased cheap and resold as originals. Most of us would not be fooled by them (as they are pretty bad) but there are plenty of vulnerable collectors out there lacking knowledge, and looking for a deal.
Ebay should really ban all of these "replica balls" immediately....
