More than likely.
A few of the lucky 100 all probably trying to make out like it's worth something so they can all sell them off.
It dont think it really sold for $600, one of the "bidders" only has 2 on the feedback
just to point out the coin is 3rd party, the guy that made it could print 1000 out tomorrow if he feels like
One of them went for £400 on eGay. Not a lot of money, but still good.

Thought if check in? Has the OP sold the coin yet?
