ebay member sent me a message claiming my item was a fake

[catawbavalleytableware]

I just put a very rare item up for a 10 day auction and less than 4 hours later had a member try to tell me  it was a fake . I know for a fact it's not a fake . I believe this member was trying to somehow get  for a very good deal on this piece . I just started listing again after taking a yr off off Ebay due to having to deal with those who try to get something for nothing  .. Anyone think this should be reported and if so - how to report it  I know this is more common than it should be , And I do enjoy selling to the Honest folk here.. What is the best way to deal with these jecks , The first thing I did was put him on my blocked buyers list .But I'd love to see Ebay give the person a Strike  

 Concerns Item #221821163826          Thanks for reading my RANT

 PS  I made this a local pickup just so I could get a signature saying it was acceptted and item was as described

  OK - HOW DO I REVISE THIS TO A CASH PAYMENT ?
 I WILL REMOVE THE RUDE COMMENT

   THanks for the replys
