The dots on yours seem to be connected, as if between each 'dot' there is a
dash connecting it.
I've never seen that on ancient coin, but then again this is a time period I don't know at all.
But, don't think of it as "just a fake," Think of it as a
replica that perhaps someone did in an
off metal (bronze instead of silver). Of course, maybe it was done in bronze too, but maybe
the purpose of having an off-metal was to indicate to the experienced collector that something
was amiss. But, I only speculate. It would be nicer if it was authentic, but it is somewhat handsome.
The
Zeus Ammon(?) figure is pretty neat.
Some dealers collect
forgeries, replicas and copies. After all, if they get burned by a forgery,
it is not ethical to pass it on. They are examples of what they should look for (or rather, against), and probably
a little humble reminder. A dealer that collects their own (authentic) coins cuts into their own profit.
But not
forgeries, replicas and copies. If they sell replicas, even as replicas, buyers might wonder.
