To make matters worse it might not even be a full team set - description say 11 cards and Cameron Smith is only featured in a separate photo to the other cards.
It does look a little sus, certainly not classic shill bidding but the secondary bidder has made over a 1000 bids on 331 items in 30 days. Perhaps makes a few bids on 0.99 cent items to cover tracks? I certainly doesn't explain the fool who paid the overs for a team set though.
Be aware that I believe that this sellers signatures are fake. John Moran signed 3 cards for me last year at the Parra players reunion and this is not his signature. Also note that the cards are all signed with the same pen and handwriting style. He only has a couple but if he gets a good price I bet more appear.
all it takes is one or two people bidding crazy and there will be an avalanche of graded cards, will be interesting... if ESP make patch cards etc i can see people getting these graded as well...
