"Counterfeit stamps are often sold in quantities of 55..."

I wonder why this is? Surely it would be relatively easy for a counterfeiter to sell them in quantities of 50 instead.

It shows how useless eBay is in policing their own site.

Assuming (as reported) the stamps are produced in China and Turkey, it would be very easy for the counterfeit sellers in the UK to simply cut off 5 stamps from each sheet, removing this obvious signal to eBay.
