I am not going to defend
eBay, but just note that
eBay has many different sites around the world, almost certainly because of the wide range of laws/regulations governing internet sales. Sellers have the option when listing items to do so only in their region (their local
eBay site) or to have it duplicated for all
eBay sites around the world.
eBay does this for the seller, even converting the
price to local currency. However, it is just one listing, and once one of these sells, all of the listings show they are sold.
When you perform a
search on
eBay, the default setting is to
search for coins only in your region of the world (that
eBay site). However, you do have the option to select the region as "Worldwide." If you do, you will likely get all the instances of that listing from all regions - now converted back to your native currency (I have seen this many times). What's crazy is as currency exchange rates change over time, the
price that looked the same when the coin was listed will show differences from the different sites. This makes it look even more suspicious, even when it is not.
