Sometimes consignors will after they were notified by
auction house or dealer that a coin is fake and they got the coin back, try to
consign the condemned coin again after a while as authentic to the same dealer or
auction house or to another dealer or
auction house. I have seen this already several times.
I assume that some of the consignors might even honestly think that the coin is authentic and that it has been condemned wrongly others consignors might know well that the coin is actually fake but they do not care.
I am not sure if the
auction house is aware of the situation that they
had withdrawn this coin already, I rather assume they forgot it und will refund you after you notify them.
