I noticed a lot more U.S. stamp sellers on
ebay are using inflated catalogue values when trying to sell their stamps.
Example: Claiming catalogue value of $30.00 for a stamp with a current Scott catalogue value of only $9.00. Of course they Never state what catalogue they are using.
I challenged one of the sellers about their stated catalogue value and he actually replied since he could not find the item in a published catalogue, he was using his own made up values.
That's FRAUD!
